The cartridge 3K forms a black image with use of black toner. Suffixes Y, M, C and K of reference symbols represent yellow, magenta, cyan and black, respectively. In the following description, in the case where there is no particular need, the suffixes Y, M, C and K are omitted in some instances. The four cartridges 3 have the same structure except for colors of developers (toners).

The cartridge 3 includes a photosensitive drum 6 as a photosensitive member. Around the photosensitive drum 6, a charging device 2, an exposure device 15, a developing device 4, a primary transfer member 5 and a cleaning device 7 are provided. The photosensitive drum 6, the charging device 2, the developing device 4 and the cleaning device 7 constitute the cartridge 3 as a unit. Above the photosensitive drum 6, an endless intermediary transfer belt (intermediary transfer member) 14 is provided. Above the intermediary transfer belt 14, a toner bottle 12 which is a toner accommodating container for accommodating the toner as the developer is provided. The toner bottle 12 is mounted so as to be mountable in and dismountable from the main assembly 1A of the image forming apparatus 1. The toner bottle 12 supplies the toner toward the developing device 4.

The primary transfer member 5 is disposed opposed to the photosensitive drum 6 through the intermediary transfer belt 14. The primary transfer member 5 transfers the toner image, on the photosensitive drum 6, onto the intermediary transfer belt 14. A secondary transfer roller (secondary transfer member) 8 is provided opposed to the follower roller 65 through the intermediary transfer belt 14 and forms a secondary transfer portion T2.

At a lower portion of the image forming apparatus 1, the feeding cassette 42 in which the sheets S are accommodated is disposed. The feeding cassette 42 is mounted in the main assembly 1 of the image forming apparatus 1 so as to be pullable toward the front side. The sheets S are fed one by one from the feeding cassette 42 by a pick-up roller 67 and a feeding roller 10. The sheet S is conveyed toward a secondary transfer portion T2 by a registration roller 9. The fixing portion 45 is disposed on a side downstream of the secondary transfer roller 8 with respect to a feeding direction of the sheet S. The fixing portion 45 is provided in a sheet conveying portion 43 with respect to a vertical direction. Between the image forming portion 44 and the image reading portion 41, a vertical path portion 19 is provided. A downstream portion of the sheet conveying portion 43 is accommodated in the vertical path portion 19. The sheet conveying portion 43 includes the feeding roller 10, the registration roller 9, the secondary transfer roller 8, the fixing portion 45, a discharging roller 18 and a reverse conveying roller 17. The sheet S is conveyed above in the vertical direction in the sheet conveying portion 43 from the secondary transfer roller 8 toward the discharging roller 18 through the fixing portion 45. With respect to the feeding direction of the sheet S, on a side downstream of the fixing portion 45, a discharge tray 13 for stacking the sheets S on which images are formed is provided. The sheets S are discharged onto the discharge tray 13 by the discharging roller 18.

The discharge tray 13 is disposed in a discharge space DS formed between the image forming portion 44 and the image reading portion 41. The discharge space DS is provided adjacent to the vertical path portion 19. The sheet S on which the images formed is discharged into the discharge space DS by the discharging roller (discharging means) 18 provided in the vertical path portion 19. The image forming apparatus is of a so-called in-body discharge type in which the sheet S on which the image is formed is discharged into the discharge space DS formed between the image forming portion 44 and the image reading portion 41.

(Image Forming Process)

Next, an image forming process of the image forming apparatus 1 will be described. Image forming processes in the four cartridges 3 are the same, and therefore, the image forming process in the yellow cartridge 3Y will be described. Description of the image forming processes in the magenta cartridge 3M, the cyan cartridge 3C and the black cartridge 3K will be omitted.

The charging device 2Y electrically charges a surface of the photosensitive drum 6Y uniformly. The exposure device 15 emits a light beam, modulated in accordance with image information of a yellow component, toward the uniformly charged surface of the photosensitive drum 6Y, and forms an electrostatic latent image on the photosensitive drum 6Y. The developing device 4Y develops the electrostatic latent image into a yellow toner image with yellow toner (developer) supplied from the toner bottle 12Y. To the primary transfer member 5y, a primary transfer bias is applied from an electric substrate (not shown). The primary transfer member 5Y primary-transfers the yellow toner image, on the photosensitive drum 6Y, onto the intermediary transfer belt 14. The toner remaining on the photosensitive drum 6Y after the primary transfer is removed by the cleaning device 7Y.

In a similar manner, the magenta toner image formed by the magenta cartridge 3M is transferred superposedly onto the yellow toner image on the intermediary transfer belt 14 with accuracy. Then, the cyan toner image and the black toner image are successively transferred superposedly onto the magenta toner image on the intermediary transfer belt 14. As a result, the four color toner images are superposed on each other on the intermediary transfer belt 14.

The sheets S accommodated in the feeding cassette 42 are fed one by one by the pick-up roller 67 and the feeding roller 10 toward the registration roller 9. The sheet S is conveyed toward the secondary transfer portion T2 by being timed to the toner images on the intermediary transfer belt 14 by the registration roller 9. The toner images on the intermediary transfer belt 14 are collectively secondary-transferred onto the sheet S by the secondary transfer roller 8. The sheet S on which the toner images are transferred is conveyed to the fixing portion 45. The fixing portion 45 fixes the toner images on the sheet S by heating and pressing the sheet S. By this, the four color toners are melted and mixed, so that a full-color image is formed on the sheet S. The sheet S on which the image is formed is discharged onto the discharge tray 13 by the discharging roller 18.

The sheet conveying portion 43 includes a reversing unit for reversing the sheet S in the case where the images are formed on double (both) surfaces (sides) of the sheet S. The reversing unit includes the reverse conveying roller 17. In the case where the images are formed on the double surfaces of the sheet S, the discharging roller 18 reverses the sheet S during discharge of the sheet S and feeds the sheet S to the reverse conveying roller 17. The sheet S turned upside down (reversed) is conveyed again to the secondary transfer portion T2 by the reverse conveying roller 17. At the secondary transfer portion T2, the toner image is transferred onto the back surface of the sheet S, and the toner image is fixed on the sheet S by the fixing portion 45. The sheet S on which the images are formed on the both surfaces is discharged onto the discharge tray 13 by the discharging roller 18.

(Image Forming Apparatus)

FIG. 8 is a sectional view of the image forming apparatus 81 of the embodiment 3. FIG. 9 is a perspective view of the image forming apparatus 81 of the embodiment 3. As shown in FIG. 8, the image forming apparatus 81 is a full-color multi-function machine of a tandem type in which image forming portions PY, PM, PC and PK are provided along an intermediary transfer belt 82. The image forming apparatus 81 is an electrophotographic image forming apparatus for forming an image on a recording material (medium) S with use of an electrophotographic type, but is not limited thereto. The image forming apparatus 81 may also be an ink jet printer. The recording material S is a transfer material on which the image is formed by the image forming apparatus 81, and for example, paper, an OHP sheet, a cloth and the like. Hereinafter, the recording material S is referred to as a sheet S.

The image forming portion PY forms a yellow image with use of yellow toner. The image forming portion PM forms a magenta image with use of magenta toner. The image forming portion PC forms a cyan image with use of cyan toner. The image forming portion PK forms a black image with use of black toner. Suffixes Y, M, C and K of reference symbols represent yellow, magenta, cyan and black, respectively. In the following description, in the case where there is no particular need, the suffixes Y, M, C and K are omitted in some instances. The four image forming portions P have the same structure except for colors of developers (toners).

The image forming portion P includes a photosensitive drum (image bearing member) 86 as a photosensitive member. The photosensitive drum 86 is rotatable in a direction indicated by an arrow R1. Around the photosensitive drum 86, a charging device 87, an optical scanning apparatus 83, a developing device 88, a primary transfer device 89 and a drum cleaning device 80 are provided. Above the photosensitive drum 86, an endless intermediary transfer belt (intermediary transfer member) 82 is provided.

The intermediary transfer belt 82 is stretched by a driving roller 92 and two follower rollers 93 and 95. The intermediary transfer belt 82 rotates in a direction indicated by an arrow R2 of FIG. 1 during image formation. The primary transfer device 89 is disposed opposed to the photosensitive drum 86 through the intermediary transfer belt 82. The primary transfer device 89 transfers the toner image, on the photosensitive drum 86, onto the intermediary transfer belt 82. A secondary transfer roller (secondary transfer member) 96 is provided opposed to the follower roller 85 through the intermediary transfer belt 82 and forms a secondary transfer portion T2.

At a lower portion of the image forming apparatus 81, the feeding cassette 102 in which the sheets S are accommodated is disposed. The feeding cassette 102 is mounted in the main assembly (hereinafter, referred to as an apparatus main assembly) 83 of the image forming apparatus 81 so as to be pullable toward the front side. Further, at a side portion of the apparatus main assembly 83, a manual feeding tray 99 is provided so as to be openable and closable. The sheet S is fed from the manual feeding tray 99 or the feeding cassette 102 by a feeding roller 97. The sheet S is conveyed toward the secondary transfer roller 96 by a registration roller 98. A fixing device 84 is disposed on a side downstream of the secondary transfer roller 86 with respect to a feeding direction of the sheet S. The fixing device 84 is provided in a vertical path portion 94. The sheet S is conveyed above in the vertical direction in the vertical path portion 94 from the secondary transfer roller 96 toward the discharging roller 95 through the fixing device 84. With respect to the feeding direction of the sheet S, on a side downstream of the fixing device 84, a discharge tray 105 for stacking the sheets S on which images are formed is provided. The sheets S passed through the vertical path portion 94 are discharged onto the discharge tray 105.

In the vertical path portion 94 below an operating portion 110, a sheet S feeding portion including the discharging roller 95, various sensors, the fixing device 84 and an air-blowing fan are accommodated. The discharge tray 105 which is an example of a stacking portion is disposed between the apparatus main assembly 83 and an image reading portion 106, and the sheets S on which the images are formed by the apparatus main assembly 103 are stacked. The user is capable of taking the sheets S on the discharge tray 105 out of the image forming apparatus from the front side.

(Image Forming Process)

Next, an image forming process of the image forming apparatus 81 will be described. Image forming processes in the four image forming portions P are the same, and therefore, the image forming process in the yellow image forming portion PY will be described. Description of the image forming processes in the magenta image forming portion PM, the cyan image forming portion PC and the black image forming portion PK will be omitted.

The charging device 2Y electrically charges a surface of the photosensitive drum 86Y uniformly. The optical scanning apparatus 103 emits a light beam, modulated in accordance with image information of a yellow component, toward the uniformly charged surface of the photosensitive drum 86Y, and forms an electrostatic latent image on the photosensitive drum 86Y. The developing device 88Y develops the electrostatic latent image into a yellow toner image with yellow toner (developer). The primary transfer device 89Y primary-transfers the yellow toner image, on the photosensitive drum 86Y, onto the intermediary transfer belt 82. The toner remaining on the photosensitive drum 86Y after the primary transfer is removed by the drum cleaning device 100Y, and the photosensitive drum 86 prepares for subsequent image formation.

In a similar manner, the magenta toner image formed by the magenta image forming portion PM is transferred superposedly onto the yellow toner image on the intermediary transfer belt 12 with accuracy. Then, the cyan toner image and the black toner image are successively transferred superposedly onto the magenta toner image on the intermediary transfer belt 82. As a result, the four color toner images are superposed on each other on the intermediary transfer belt 82.

The sheet S fed from the feeding cassette 102 or the manual feeding tray 99 is conveyed toward the secondary transfer roller 96 by being timed to the toner images on the intermediary transfer belt 82 by the registration roller 98. The four color toner images superposed on the intermediary transfer belt 82 are collectively secondary-transferred onto the sheet S by the secondary transfer roller 96. The sheet S on which the toner images are transferred is conveyed to the fixing device 84. The fixing device 84 fixes the toner images on the sheet S by heating and pressing the sheet S. The sheet S on which the image is formed is discharged onto the discharge tray 105 by the discharging roller 95.

(Image Reading Portion)

Above the main assembly 83, the image reading portion (flat head scanner) 106 is disposed through the vertical path portion 94. The image reading portion 106 is operable in a manual reading mode (fixed reading mode) and an automatic reading mode (skim through mode). In the manual reading mode, the user raises an automatic document feeder (ADF) 107 and places the original on the reading surface 106a. The image reading portion 106 optically reads an image on a lower surface of an original placed on a reading surface (glass plate) 106a and converts the image into the image data. In the automatic reading mode, the automatic document feeder 107 separates originals one by one from a batch of originals stacked on an original tray 108 and feeds the original to the reading surface 106a. The image reading portion 106 optically reads an image of the original fed on the reading surface 106a and converts the image into image data.

(Operating Portion)

The image forming apparatus 81 is provided with the operating portion 46 for permitting the user to input information or an instruction and to operate the image forming apparatus 81. The operating portion 46 is similar to that described in the embodiment 1, and therefore will be omitted from description.

(Communication Device)

Next, using FIG. 9 and FIG. 10, a communication device 121 and a fifth communication device 131 will be described. The communication device 121 in this embodiment corresponds to the first communication device 31 in the embodiment 1. Further, the communication device 131 in this embodiment corresponds to the second communication device 32 or the third communication device in the embodiment 1. FIG. 10 is a front view of the image forming apparatus 81. The communication device 121 and the communication device 131 include near-range (field) wireless communication means, respectively. The information terminal device 52 is a storing device for storing information. The communication device 121 connectable with the information terminal device 52 through the near-field wireless communication (hereinafter, referred to as NFC) is disposed inside a vertical path portion cover 104 similarly as in the embodiment 1. A front surface of the vertical path portion cover 104 is a substantially flat surface and is substantially flush with a forefront surface of a front cover 130 of the image forming apparatus 81 and a forefront surface of the image reading portion 106 or is positioned in front of these surfaces. Further, substantially at a central portion of the front surface (outer appearance surface) of the vertical path portion cover 104, a circular target display portion 122 which is a mark for causing the user to bring (hold) the information terminal device 52 near to (over) the communication device 121 is formed by silk(-screen) printing. The target display portion 122 is a target display targeted by the user when the user brings the information terminal device 52 near to the communication device 121 in order to receive information from the communication device 121 through the NFC. The information terminal device 52 is connected with the communication device 121 through the NFC when is brought near to the target display portion 122. The target display portion 122 is provided on a side wall surface (side surface) of the image forming apparatus 81.

The information terminal device 52 an NFC-compatible mobile device. The NFC-compatible mobile device is, for example, an NFC-compatible cellular (mobile) phone, a smartphone, a tablet terminal, a tablet personal computer, an NFC-compatible camera, an NFC-compatible video camera and an NFC-compatible notebook(-size) personal computer. A communication area of the NFC connecting the information terminal device 52 with the communication device 121 is from several centimeters to about 1 meter in communication distance. The NFC connecting the information terminal device 52 with the communication device 121 is, for example, the Wi-Fi (registered trademark) or the Bluetooth (registered trademark). The Wi-Fi (registered trademark) is interconnection between devices in conformity with the Wireless communication standard IEEE 802.11 in which wireless communication is performed using 2.4 GHz band, 5 GHz band or 60 GHz band. The Bluetooth (registered trademark) is interconnection between devices in conformity with the Wireless communication standard IEEE 802.15.1 in which wireless communication is performed using 2.4 GHz band.

For example, an application software (hereinafter, referred to as application) is installed in the information terminal device 52, and the application is lunched. By operating the information terminal device 52 toward the target display portion 122 in an arrow A direction, the information terminal device 52 is connected with the communication device 121 through the NFC. A direction in which the information terminal device 52 is operated toward the target display portion 122 is not limited to the arrow A direction, but may also be a direction from left to right, a direction from right to left, and a direction from below to above. The direction in which the information terminal device 52 is operated toward the target display portion 122 is different from a direction in which the user operates the operating portion 110 from above to below. An access direction of the information terminal device 52 to the target display portion 122 is different from an access direction of the user to the operating portion 110, so that misoperation of the image forming apparatus 81 due to access of the information terminal device 52 can be prevented.

As shown in FIG. 10, the target display portion 122 of the communication device 121 is provided at the forefront surface of the image forming apparatus 81. When the user operates the information terminal device 52 toward the first target display portion 122 in the arrow A direction, there is no obstacle to the operation at the front surface (front side) of the image forming apparatus 81, so that the user is capable of authenticating the information terminal device 52 by the communication device 121 with accuracy. In the case where the information terminal device 52 is, for example, a tablet terminal having a screen size of about 254 mm (10 inches) in diagonal line, a projection area of the information terminal device 52 is relatively large. Even in the case where such a tablet terminal is operated toward the first target display portion 122 in the arrow A direction, a relatively broad space is ensured in front of the vertical path portion cover 104 on which the first target display portion 122 is formed, so that operativity is improved. According to this embodiment, even in the case where the information terminal device 52 having the relatively large area is operated, the operativity is satisfactory, so that the communication device 121 is capable of communicating with the information terminal device 52 with reliability.

As shown in FIG. 9, the fifth communication device 131 connectable with the information terminal device 52 through the NFC is disposed above the vertical path portion cover 104. The information terminal device 52 is the storing device for storing the information. The firth communication device 131 acquires the information from the information terminal device 52 through the NFC. The fifth communication device 131 is disposed beside the operating portion 110. Specifically, the fifth communication device 131 is disposed on the right side of the operating portion 110 and inside an upper right cover 201 provided at an upper portion of the vertical path portion cover 104. At a substantially central portion of an upper surface of the upper right cover 201, a circular target display portion 132 which is a mark for causing the user to bring (hold) the information terminal device 52 near to (over) the fifth communication device 31 is formed by silk(-screen) printing. The second target display portion 132 is provided at a position different from the first target display portion 122. The second target display portion 132 is disposed beside the touch panel of the operating portion 110. The second target display portion 132 in this embodiment is disposed adjacent to the operating portion 110 with respect to a left-right direction relative to a front-rear direction of the image forming apparatus 81. As shown in FIG. 9, the second target display portion 132 is adjacent to the manual feeding tray 99 side relative to the operating portion 110. Further, the user operates the information terminal device 52 from above the image forming apparatus 81 toward the second target display portion 132 in an arrow B direction. When the information terminal device 52 is brought near to (opposed to) the second target display portion 132, the information terminal device 52 performs the wireless communication with the fifth communication device 131 through the NFC.

The NFC-communication device IC card is, for example, a thin plate having a dimension of about 85 mm in vertical length and about 55 mm in lateral length. The NFC-compatible IC card is smaller in dimension than the NFC-compatible mobile device. Accordingly, even when the user operates the information terminal device 52 toward the fifth communication device 132 in the direction indicated by the arrow B, the information terminal device 52 itself and fingers (of the user) holding the information terminal device 52 are not close to the touch panel of the operating portion 110, and therefore, the fingers do not readily contact the touch panel. Even when the fifth communication device 131 is provided beside the touch panel of the operating portion 110, an occurrence of misoperation of the image forming apparatus 81 due to the operation of the information terminal device 52 is reduced. Further, the IC card is held in a holder provided with a strap for being put on user's neck or held in a holder provided with a reel in many instances. When the second target display portion 132 is provided on the side surface of the image forming apparatus 81, users using holders with a short length of the strap or with a short length of the reel have to perform a stooping operation for causing the IC card to face the second target display portion 132, so that it is not preferable from the viewpoint of usability. For that reason, in this embodiment, the second target display portion 132 is provided on a side above the first target display portion 122 in the vertical direction.

The communication device 121 is disposed in the neighborhood of the communication device 131. Therefore, wiring of the communication device 121 and wiring of the fifth communication device 131 can be connected with a controller substrate provided at a rear portion of the image forming apparatus 81 through an inside of the same space.

A position where the communication device 121 is disposed is different from a position where the fifth communication device 131 is disposed. The position where the communication device 121 is disposed is distant from the operating portion 110 more than the position where the fifth communication device 131 is disposed is. According to this embodiment, it is possible to suppress that the misoperation of the image forming apparatus 81 occurs when the user holds the information terminal device 52 over the communication device 121.

Embodiment 4

Next, with reference to FIG. 11, an embodiment 4 will be described. FIG. 11 is a right side view of the image forming apparatus 111 of the embodiment 3. In the embodiment 3, structures similar to those in the embodiment 3 will be omitted from description by adding similar reference symbols thereto. The image forming apparatus 111 of the embodiment 4 has a structure substantially similar to the image forming apparatus 81 in the embodiment 3 and therefore will be omitted from description. The communication device 121 in the embodiment 4 is the same as the communication device 121 in the embodiment 3 and therefore will be omitted from the description. However, a locating position of the communication device 121 in the embodiment 4 is different from a locating position of the communication device 121 in the embodiment 3. In the following, the locating position of the communication device 121 in the embodiment 4 will be described.

(Communication Device)

The target display portion 122 in the embodiment 3 is formed on the vertical path portion cover 104 which is the forefront surface (side) of the image forming apparatus 81. On the other hand, a target display portion 142 in the embodiment 4 is formed on a right side wall surface of the image forming apparatus 111. Specifically, the communication device 121 is disposed inside a right front vertical cover 141. A right side surface of the right front vertical cover 141 is a substantially flat surface and is substantially flush with other right side covers of the image forming apparatus 111 or is positioned on an outermost side of the right side (surface) of the image forming apparatus 111. The communication device 131 is disposed on the right side of the operating portion 110 and inside the upper right cover 201 similarly as in the embodiment 3.

The manual feeding tray 99 is mounted on the right side (surface) of the image forming apparatus 111 so as to be openable and closable. The image forming apparatus 111 is of a vertical path type in which the sheet S is fed from below to above, and therefore, a relatively broad flat surface portion can be provided on the right side surface of the image forming apparatus 111. Accordingly, a degree of freedom that a space for accommodating the communication device 121 is provided inside the right side surface of the image forming apparatus 111 and a degree of freedom that the target display portion 142 is disposed on the right side surface of the image forming apparatus 111 are provided. Further, by providing the target display portion 142 on the right side surface of the image forming apparatus 111, the user can bring the information terminal device 52 near to the target display portion 142 in a state in which the user stands on the front side of the image forming apparatus 111. The operating portion 110 is disposed on the front side of the image forming apparatus 111, so that the target display portion 142 is disposed on the right side surface of the image forming apparatus 111 and on a side (front side) closer to the front surface than the operating portion 110 is. The first target display portion 142 is disposed close to the operating portion 110, so that operativity to the image forming apparatus 111 by the user is improved.

For example, an application software installed in the information terminal device 52 is lunched, and by operating the information terminal device 52 toward the target display portion 142 in an arrow C direction, the information terminal device 52 is connected with the communication device 121 through the NFC. A direction in which the information terminal device 52 is operated toward the target display portion 142 is not limited to the arrow C direction, but may also be a direction from right front to right rear, a direction from right rear to right below, a direction from right below to right above, and a direction from right above to right below. The direction in which the information terminal device 52 is operated toward the target display portion 142 is different from a direction in which the user operates the operating portion 110 from above to below. An access direction of the information terminal device 52 to the target display portion 142 is different from an access direction of the user to the operating portion 110, so that the information terminal device 52 itself does not contact the operating portion 110. Further, fingers (of the user) holding the information terminal device 52 do not contact the operating portion 110 or are prevented from being near to the operating portion. Therefore, misoperation of the image forming apparatus 111 due to access of the information terminal device 52 to the target display portion 142 can be suppressed.

A position where the communication device 121 is disposed is different from a position where the communication device 131 is disposed. The position where the communication device 121 is disposed is distant from the operating portion 110 more than the position where the communication device 131 is disposed is. According to this embodiment, it is possible to prevent that the misoperation of the image forming apparatus 111 occurs when the user holds the information terminal device 52 over the communication device 121.

Embodiment 5

Next, with reference to FIG. 12, an embodiment 5 will be described. FIG. 12 is a left side surface of the image forming apparatus 151 of the embodiment 5. In the embodiment 5, structures similar to those in the embodiment 3 will be omitted from description by adding similar reference symbols thereto. The image forming apparatus 151 of the embodiment 5 has a structure substantially similar to the image forming apparatus 81 in the embodiment 3 and therefore will be omitted from description. The communication device 121 in the embodiment 5 is the same as the communication device 121 in the embodiment 3 and therefore will be omitted from the description. However, a locating position of the communication device 121 in the embodiment 5 is different from a locating position of the communication device 121 in the embodiment 3. In the following, the position where the communication device 121 in the embodiment 5 is disposed will be described.

(Communication Device)

The target display portion 122 in the embodiment 3 is formed on the vertical path portion cover 104 which is the forefront surface (side) of the image forming apparatus 81. The target display portion 142 in the embodiment 4 is formed on the right front vertical cover 141 which is the outermost surface of the right side surface of the image forming apparatus 111. On the other hand, a target display portion 222 in the embodiment 5 is formed on a left side wall surface of the image forming apparatus 151. Specifically, the communication device 121 is disposed inside a left device 102. The left cover 102 is a substantially flat surface and is substantially flush with other left side covers of the image forming apparatus 151 or is positioned on an outermost side of the left side wall surface of the image forming apparatus 151. The communication device 131 (not shown in FIG. 5) is disposed on the right side of the operating portion 110 and inside the upper right cover 201 similarly as in the embodiment 3.

The left cover 102 is fixed on the left side of the image forming apparatus 151. The left device 102 occupies a large area on the left side (surface) of the image forming apparatus 151. Accordingly, a degree of freedom that a space for accommodating the communication device 121 is provided inside the left side surface of the image forming apparatus 151 and a degree of freedom that the target display portion 222 is disposed on the left side surface of the image forming apparatus 151 are provided. Further, by providing the first target display portion 222 on the left side surface of the image forming apparatus 151, the operativity of the information terminal device 52 to the first target display portion 222 is also good. The operating portion 110 is disposed on the front side of the image forming apparatus 151, so that the first target display portion 222 is disposed on the left side surface of the image forming apparatus 151 and on a side (front side) closer to the front surface than the operating portion 110 is. The user can bring the information terminal device 52 near to the target display portion 142 in a state in which the user stands on the front side of the image forming apparatus 111.

For example, an application software installed in the information terminal device 52 is lunched, and by operating the information terminal device 52 toward the first target display portion 222 in an arrow D direction, the information terminal device 52 is connected with a first communication device 221 through the NFC. A direction in which the information terminal device 52 is operated toward the target display portion 222 is not limited to the arrow D direction, but may also be a direction from left front to left rear, a direction from left rear to left front, a direction from left below to left above, and a direction from left above to left below. The direction in which the information terminal device 52 is operated toward the target display portion 222 is different from a direction in which the user operates the operating portion 110 from above to below. An access direction of the information terminal device 52 to the target display portion 222 is different from an access direction of the user to the operating portion 110, so that the information terminal device 52 itself does not contact the operating portion 110. Further, fingers (of the user) holding the information terminal device 52 do not contact the operating portion 110 or are prevented from being near to the operating portion. Therefore, misoperation of the image forming apparatus 151 due to access of the information terminal device 52 to the target display portion 222 can be prevented.

A position where the communication device 121 is disposed is different from a position where the communication device 131 is disposed. The position where the communication device 121 is disposed is distant from the operating portion 11 more than the position where the communication device 131 is disposed is. According to this embodiment, it is possible to prevent that the misoperation of the image forming apparatus 151 occurs when the user holds the information terminal device 52 over the communication device 131.

The operating portions 110 in the embodiment 3 to the embodiment 5 are, as shown in FIG. 8 to FIG. 12, small relative to sizes of the image forming apparatuses 81, 141 and 151. On the other hand, from the viewpoint of improvement in operativity, a display input portion of the operating portion 110 is upsized in some instances. With this, the operating portion 110 itself becomes large, but the target display portions 122 and 222 are positioned on the outermost surfaces on the front side, the right side and the left side of the apparatus main assembly 83 excluding the operating portion 110. Accordingly, the operativity of the information terminal device 52 to the first target display portions 121, 142 and 222 is improved while maintaining an outer appearance quality of the image forming apparatuses 81, 141 and 111, so that communication with the information terminal device 52 by the communication device 121 can be performed with reliability.

Further, in the embodiment 3 to the embodiment 5, the target display portions 121, 142 and 222 are drawn by the circles, but any notation such as illustration, symbols, characters, and the like within a range in which the user can recognize that the notation is a target portion for the information terminal device 52.

On the discharge tray 105, as an option, an in-body finisher (not shown) may also be provided. Or, on the discharge tray 105a, a buffer path unit (not shown) as an option is provided, and the buffer path unit (not shown) may also deliver the sheet S to an external finisher attached to an outside of the image forming apparatuses 81, 141 and 151. In that case, the first target display portion is disposed on at least one side wall surface of all direction side surfaces of the image forming apparatuses 81, 141 and 151 including options. When the information terminal device 52 is operated toward the target display portion 122 of the communication device 121, the information terminal device 52 can be caused to communicate with the first communication device 121 without preventing operativity thereof by the options.

According to the above-described embodiment, the target display portion of the communication device capable of the near-range (field) wireless communication is disposed on at least one side surface excluding the rear surface of the all direction side surfaces of the image forming apparatus. When a device-to-be-authenticated is operated from the side surface of the image forming apparatus toward the target display portion of the communication device, the operation is not hindered by an obstacle such as a configurational projection from the image forming apparatus, improvement of the operativity is realized. Further, in the case where the access direction to the operating portion is from substantially above the image forming apparatus, the device-to-be-authenticated has access to the target display portion in a direction different from the access direction to the operating portion, so that erroneous input to the operating portion is prevented.

Even when in order to improve the operativity of the image forming apparatus, the display portion of the operating portion becomes a large size and thus the operating portion itself becomes large, the target display portion is disposed on the outermost surface of at least one side surface of the apparatus main assembly excluding the operating portion. By this, the target display portion has no influence on an entire outer appearance excluding the operating portion.

The operating portion is disposed on the front side of the image forming apparatus, and the target display portion is provided at least one of a forward side (front side) of the left side surface toward the operating portion and a forward side (front side) of the right side surface toward the operating portion. By this the target display portion is provided within a range in which the user's hand operating the operating portion reaches, so that the operativity as a whole of the image forming apparatus is improved.

According to the above-described embodiment, it is possible to prevent an occurrence of misoperation when the user holds the mobile device over the communication device.

INDUSTRIAL APPLICABILITY

According to the present invention, an image forming apparatus in which contact, with the operating portion of the image forming apparatus, of the information terminal device held by the user over the operating portion is suppressed is provided.
