In the black visible-image-formation-unit UK, an image supporter Pk is surrounded by a charger CCk, a developing device Gk, an image supporter cleaner CLk, etc.
Image supporters Py, Pm, and PC of other visible-image-formation-units UY, UM, and UC are also surrounded by chargers CCy, CCm, and CCc, developing devices Gy, Gm, and Gc, image supporter cleaners CLy, CLm, and CLc, etc., like those surrounding the image supporter Pk.
In
The visible images on the surfaces of the image supporters Py, Pm, Pc, and Pk are transferred in order onto an intermediate transfer belt B as an example of an intermediate transfer body in an overlap manner by primary transfer members T1y, T1m, T1c, and T1k as an example of primary transfer devices and a multicolor image is formed on the intermediate transfer belt B. The multicolor image formed on the intermediate transfer belt B is conveyed to a secondary transfer area Q4.
To form only a single-color image, only the black (K) image supporter Pk and the black (K) developing device Gk are used and only a black visible image is formed.
After the primary transfer, the residues on the surfaces of the image supporters Py, Pm, Pc, and Pk are removed and cleaned by the image supporter cleaners CLy, CLm, CLc, and CLk.
The intermediate transfer belt B is supported for rotation in an arrow Ya direction by an intermediate transfer body drive member Rd, a tension generation member Rt, a meandering prevention member Rw, a plurality of driven members Rf, a secondary transfer opposed member T2a, and the primary transfer members T1y, T1m, T1c, and T1k. In the first exemplary embodiment, the members Rd, Rt, Rw, Rf, T2a, T1y, T1m, T1c, and T1k are each formed of a roll-like member.
A secondary transfer unit Ut is placed below the backup roll T2a as an example of the secondary transfer opposed member. A secondary transfer member T2b of the secondary transfer unit Ut is placed so that it can be brought into and out of contact with the backup roll T2a with the intermediate transfer belt B between, and the area where the secondary transfer member T2b is pressed against the intermediate transfer belt B forms a secondary transfer area Q4. In the first exemplary embodiment, a contact conducting member T2c is abutted against the backup roll T2a and a secondary transfer voltage of the same polarity as the charge polarity of the developer is applied to the contact feeding member T2c at a predetermined timing from the power supply circuit E controlled by the control section C.
The secondary transfer opposed member T2a, the secondary transfer member T2b, and the contact feeding member T2c make up a secondary transfer device T2 of the first exemplary embodiment, and the primary transfer members T1y, T1m, T1c, and T1k, the intermediate transfer belt B, and the secondary transfer device T2 make up a transfer unit of the first exemplary embodiment.
A sheet conveying passage SH2 is placed below the intermediate transfer belt B. A record sheet S fed from the sheet feed passage SH1 of the sheet feed unit U2 is conveyed to a registration roll Rr as an example of a sheet feed timing adjustment member of the conveying passage SH2. A medium-pattern-information-reader SN1 is placed in the conveying passage SH2 for reading pattern information of the surface of the record sheet S or so-called paper fingerprint when the record sheet S passes through. The medium-pattern-information-reader SN1 of the first exemplary embodiment is placed so as to cover the maximum sheet width of the passing record sheet S and can read the paper fingerprint in the whole area of the maximum sheet width.
The record sheet S conveyed to the registration roll Rr is conveyed through a before-transfer upstream medium guide member SGr and a before-transfer downstream medium guide member SG1 to the secondary transfer area Q4 at the timing at which a multicolor image is conveyed to the secondary transfer area Q4.
When the multicolor image on the intermediate transfer belt B is conveyed to the secondary transfer area Q4 passes through the secondary transfer area Q4, the multicolor image is transferred to the record sheet S by the secondary transfer device T2. For the multicolor image, the toner images primarily transferred to the surface of the intermediate transfer belt B in an overlap manner are secondarily transferred to the record sheet S collectively.
After the secondary transfer, the intermediate transfer belt B is cleaned by an intermediate transfer body cleaner CLB. The secondary transfer member T2b and the intermediate transfer body cleaner CLB are disposed so that they can be brought into and out of contact with the intermediate transfer belt B. To form a multicolor image, they are placed out of contact with the intermediate transfer belt B until an unfixed visible image of the final color is primarily transferred to the intermediate transfer belt B.
The record sheet S to which an unfixed visible image is secondarily transferred is conveyed through an after-transfer medium guide member SG2 and a medium conveying member BH to a fixing unit F. This fixing unit F has a heating roll Fh as an example of a heating fixing member and a pressurization roll Fp as an example of a pressurization fixing member, and the record sheet S is conveyed to a fixing area Q5 where a pair of fixing members Fh and Fp come in contact with each other in a state in which a pressure acts. When the unfixed visible image on the record sheet S passes through the fixing area Q5, it is heated and fixed by the fixing unit F. A switching member G1 is provided downstream from the fixing unit F. The switching member G1 selectively switches the record sheet S conveyed on the conveying passage SH2 and heated and fixed in the fixing area Q5 to either a discharge passage SH3 or an inversion passage SH4. The record sheet S conveyed to the discharge passage SH3 is discharged from a discharge roller Rh as an example of a discharge member to the post-treatment unit U4.
A circulating passage SH5 is connected to the inversion passage SH4 and a conveying direction regulation member G2 is provided in the connection part. The conveying direction regulation member G2 allows the record sheet S conveyed to the inversion passage SH4 to once pass through as it is, and conveys the passing record sheet S in an opposite direction and conveys the record sheet S to the circulating passage SH5. The record sheet S conveyed to the circulating passage SH5 is again sent to the secondary transfer area Q4 through the sheet feed passage SH1.
The components SH1 to SH5 make up a medium conveying passage SH. The components SH, Ra, Rr, Rh, SG1, SG2, SGr, BH, G1, and G2 make up a medium conveying unit SU.
(Post-treatment Unit U4)
In
The record sheet S conveyed to the upper end discharge passage SH6 is discharged from an upper end discharge port P0 by an upper end discharge member 4 without being subjected to post-treatment.

At ST22, the medium S is read through the scanner section V1 of the copier V and print-image-with-medium-pattern-information-determination-information printed on the medium S is read. Then, the process goes to ST23.
At ST23, the following (1) and (2) are executed and then the process goes to ST24:
At ST24, inquiry information containing the read collation pattern information and the identification information of the medium S contained in the medium-pattern-information-determination-information is transmitted to the management apparatus 2. Then, the process goes to ST25.
At ST25, whether or not collation result information transmitted from the management apparatus 2 in response to the inquiry information is received is determined. If the determination result is Yes (Y), the process goes to ST26; if the determination result is No (N), ST25 is repeated.
At ST26, the received collation result is displayed on the display section Uva. Then, the process returns to ST21.
(Operation of First Exemplary Embodiment)
Upon reception of image information, the image formation system S0 of the first exemplary embodiment including the configuration described above expands the image information into a print image and sets a read area 13 of medium pattern information, for example, paper fingerprint from the provided print image. At this time, an area of a blank image is read based on print setting information, an image is not formed in the paper fingerprint read area 13 at the printing time and it is made possible to reliably read paper fingerprint on the medium S after print. The image formation system S0 of the first exemplary embodiment prints information of the read paper fingerprint and information of the position at which the paper fingerprint is read on the medium S as the medium-pattern-information-determination-information.
The image formation system S0 of the first exemplary embodiment reads the medium S on which the medium-pattern-information-determination-information is printed by the copier V, thereby reading the medium-pattern-information-determination-information, and reads the paper fingerprint in the pattern-information-read-area 13 based on the medium-pattern-information-determination-information and executes collation. The paper fingerprint is information almost unique to each medium S and cannot actually be copied. If paper fingerprint is read and the print image 11 of the medium S into which the medium-pattern-information-determination-information image 14a is written is copied when the medium-pattern-information-determination-information image 14a of the medium S copied is read and is collated with the paper fingerprint in the medium-pattern-information-read-area 13, the paper fingerprint does not match the paper fingerprint determined by the medium-pattern-information-determination-information image 14a and thus it is determined that the medium S is copied medium S and is not the original. On the other hand, if the medium S is the original, the paper fingerprint in the medium-pattern-information-read-area 13 matches the paper fingerprint determined by the medium-pattern-information-determination-information image 14a and thus it is determined that the medium S is the original. Therefore, the image formation system S0 of the first exemplary embodiment determines whether or not the medium S to be collated is the original by collating the paper fingerprint in the pattern-information-read-area 13 determined by the read medium-pattern-information-determination-information with the paper fingerprint registered in the management-information-storage-unit C22.
The image formation system S0 of the first exemplary embodiment prints the medium-pattern-information-determination-information image 14a in yellow hard to view by a human being and thus unless a human being observes carefully, it is difficult for the human being to recognize formation of the medium-pattern-information-determination-information image 14a.
Further, since the image formation system S0 of the first exemplary embodiment encrypts the medium-pattern-information-determination-information image 14a, it is difficult to recognize the medium-pattern-information-read-area 13 without decryption and a dishonest act of cutting the medium-pattern-information-read-area 13 of the original and putting it on a copy, for example, is hard to execute.
Next, a second exemplary embodiment of the invention will be discussed. Components identical with or similar to those of the first exemplary embodiment described above are denoted by the same reference numerals in the description of the second exemplary embodiment and will not be discussed again in detail. The second exemplary embodiment differs from the first exemplary embodiment only in the following point:

A setting technique of the medium-pattern-information-read-area 13 is set as in the first exemplary embodiment.
C6′: Medium-pattern-information-determination-information-write-area-setting-unit
Unlike the medium-pattern-information-determination-information-write-area-setting-unit C6 of the first exemplary embodiment, the medium-pattern-information-determination-information-write-area-setting-unit C6′ sets a medium-pattern-information-determination-information-write-area 14 based on the readable areas 12 determined by the received readable area information. Others are set in a similar manner to that in the first exemplary embodiment.
