Description
FIELD OF THE INVENTION
This invention relates to a bisstyryl compound and the electrophotographic photoreceptors relating thereto and, particularly, to the bisstyryl compound suitable for a carrier transporting material in an electrophotographic photoreceptor comprising a photoreceptive layer containing a carrier generating material and the carrier transporting material.
BACKGROUND OF THE INVENTION
As for an electrophotographic photoreceptor, those containing each an inorganic photoconductor such as selenium, zinc oxide, cadmium sulfide and silicon as the principal component have heretofore been widely known. However, their characteristics such as the thermal stability and durability thereof have not always been satisfactory and they have also had the problems of manufacture and handling.
On the other hand, the photoreceptors comprising each a photoreceptive layer containing an organic photoconductive compound as the principal component thereof are relatively easier for manufacture, inexpensive in cost, easier for handling and, generally, excellent in thermal stability as compared to a selenium photoreceptor. As for the organic photoconductive compounds, a poly-N-vinylcarbazole has been well-known. There have already been put to practical use the photoreceptors comprising each a photoreceptive layer containing an electric-charge transfer complex produced of the above-mentioned poly-N-vinylcarbazole and a Lewis acid such as 2,4,7-trinitro-9-fluorenone as the principal component thereof.
Further, on the other hand, there have also been known a photoreceptor comprising a laminated or single layered function-separated type photoreceptive layer in which the carrier generating function and carrier transporting function of the photoconductor thereof can be performed by separate materials, respectively. For example, there have already been put to practical use the photoreceptors comprising each a photoreceptive layer comprising a carrier generating layer formed of a thin amorphous selenium layer and a carrier transporting layer containing a poly-N-vinylcarbazole as the principal component thereof.
However, the above-mentioned poly-N-vinylcarbazole lacks a flexibility and the coated layer thereof is solid and fragile and is liable to be cracked or peeled off. Every photoreceptor applied therewith is, therefore, deteriorated in durability. When the above-mentioned defects are improved by adding a plasticizer, the residual potentials are increased in an electrophotographic process and are accumulated as in making repetition use so as to produce fogs increasingly, so that a copied image is spoiled.
A low-molecular organic photoconductive compound has generally no coated-layer forming function. Therefore, when the compound is used with a suitable binder in combination and the kinds and composite proportions of the binders are suitably selected, the compound is preferable from the viewpoint that the physical properties of the coated layer or the photoreceptive characteristics can each be controlled to some extent. However, there are some limitation to the kinds of the organic photoconductive compounds each having a relatively high compatibility with the binders. Actually, there are limited to the kinds of the binders applicable to form the photoreceptive layers of an electrophotographic photoreceptor.
For example, 2,5-bis(p-diethylaminophenyl)-1,3,4-oxadiazole described in U.S. Pat. No. 3,189,447 is low in compatibility with the binders commonly applicable as a material of the photoreceptive layers of an electrophotographic photoreceptor, such as a polyester and a polycarbonate. In other words, when a photoreceptive layer is formed by mixing them up in a proportion required for controlling the electrophotographic characteristics, the crystals of oxadiazole are deposited at a temperature of not lower than 50.degree. C., so as to have a defect that the electrophotographic characteristics such as electric-charge coercive force and photoreceptivity deteriorate.
In the meanwhile, each of the diaryl alkane derivatives described in U.S. Pat. No. 3,820,989 has few problems of the compatibility with a binder. However, it is low in stability against light. When it is applied to a repetition-transfer type electrophotographic photoreceptor to which an electric-charge.multidot.an exposure are applied repeatedly, it has a defect that the photoreceptivity of the photoreceptive layer is gradually lowered.
In U.S. Pat. No. 3,274,000 and Japanese Patent Examined Publication No. 47-36428/1972, the different types of phenothiazine derivatives are described, respectively. However, every one of them has the defect that the photoreceptivities thereof are low and the stabilities thereof are also low in repetition use.
The stilbene compounds described in Japanese Patent Publication Open to Public Inspection (hereinafter referred to as JP OPI Publication) Nos. 58-65440/1983, 58-190953/1983 and 63-149652/1988 are each relatively excellent in electric-charge coercive force and photoreceptivity. However, they are still not satisfactory in durability in repetition use.
In the meanwhile, the photoreceptors capable of solving the above-mentioned defects include those applied with a distilbene compound as the carrier transporting material thereof, such as those described in JP OPI Publication Nos. 60-175052/1985, 60-174749/1985, 62-120346/1987, 64-32265/1989, 1-106069/1989, 1-93746/1989 and 1-274154/1989. However, they can still not be satisfactory in durability when they are incorporated into a copier or a printer and are used repeatedly.
Particularly, there have been the following for problems.
1) In a high-speed copier having a high linear velocity, a cycle of electric-charging.multidot.exposure.multidot.electric neutralization is shortened. Therefore, the residual potential is seriously raised in repetition copying operations;
2) When making use of a copier for repeating copying operations, a small white spotted image defect (that is so-called a white-dot) is produced in solid-black image areas;
3) When making use of a reversal development type printer, there found the defects that an exposure potential (VL) is raised at a low temperature and an electric-charge potential (VH) is lowered in repetition use; and
4) A small black-spotted image defect (that is so-called a black-dot) is liable to be produced in white image areas.
As described above, there has not been found any carrier transporting material having the characteristics which can be practical and satisfactory for providing an electrophotographic photoreceptor.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a compound suitable for a carrier transporting material for a highly photoreceptive and highly durable photoreceptor applicable to a copier or printer and the electrophotographic photoreceptors relating thereto.
The other objects of the invention are to provide the following (1) through (4);
(1) a compound suitable for a carrier generating material for a photoreceptor not raising any residual potential thereof even when repeating a series of electric-charging.multidot.exposure.multidot.electric neutralization operations, in a high-speed copier having a high linear velocity, and the electrophotographic photoreceptors relating thereto;
(2) a compound suitable for a carrier transporting material for a photoreceptor not producing any small white-spotted image defect (that is so-called a white-dot) in the solid-black image areas even in repetition use, when the photoreceptor is incorporated into a copier, and the electrophotographic photoreceptors relating thereto;
(3) a compound suitable for a carrier generating material for a photoreceptor neither raising an exposure potential (VL) at a low temperature even in repetition use, nor lowering an electric-charge potential (VH) even in repetition use, in the case where the photoreceptor is incorporated into a reversal development type printer, and the electrophotographic photoreceptors relating thereto; and
(4) a compound suitable for a carrier transporting material for a photoreceptor not producing any small black-spotted image defect (that is so-called a black-dot) in the white image areas, and the electrophotographic photoreceptors relating thereto.

EVALUATION EXAMPLE 1
The residual potentials Vr were each measured when a series of electric-charging.multidot.Exposing operations were repeated 20,000 times by making use of a copier, modified U-Bix Model 5076 manufactured by Konica Corp. (in which the charging electrode was changed to be negative and the exposure amount was changed into 4.65 lux) and by changing the linear velocities into 3 velocities, namely 240, 330 and 440 mm/sec. The results of the measurements are shown in the following Tables-8 through 10. The residual potentials of the photoreceptors applied with the CTM of the invention did not become intense when the linear velocities were made faster than those of the photoreceptors applied with the comparative compounds, so that an excellent high velocities were shown. In the meanwhile, the initial white-paper potentials (Vw) were each shown in Tables-8 through 10.
EVALUATION EXAMPLE 2
The 100,000 times continuous copying tests were tries by making use of A-4 size regenerated paper and the copier, modified U-Bix Model 5076 manufactured by Konica Corp., which was the same as in Evaluation Example 1. The results thereof are shown in the following Tables-11 through 13. The photoreceptors applied with the compounds of the invention provided excellent images upto the 100,000th copy and, on the other hand, the comparative photoreceptors produced several white-dots in the solid-black image areas after the 20,000 to 30,000th copying tests. The white-dots were evaluated by visually counting the numbers of the white-dots produced on a solid-black image in A-4 size. The results thereof are shown in Tables-11 through 13.
EVALUATION EXAMPLE 3
The resulting electric potential in an unexposed area VH and electric potential in an exposed area VL were each measured at an ordinary temperature (of 25.degree. C.) and a low temperature (of 10.degree. C.) by making use of a digital copier, U-Bix Model 8028 manufactured by Konica Corp. The results thereof are shown in the following Tables-14 through 17.
EVALUATION EXAMPLE 4
The resulting black-dots produced in the white-background of a copied image were evaluated after making use of the digital copier, U-Bix Model 8028 manufactured by Konica Corp., which was the same as that used in the above-described Evaluation Example 3, loading the subject photoreceptor into a developer and then image-copying several times. The results thereof are shown in the following Tables-18 through 21.
The resulting black-dots were evaluated by measuring the dot-sizes and numbers of the black-dots through an image analyzer, `Omnicon Model 300` (manufactured by Shimazu Mfg. Works). The results were judged by counting the numbers of the resulting black-dots having a size .0. of not smaller than 0.05 mm in one cm.sup.2. The judgement criteria of evaluating the black-dots are shown in the following table.
TABLE______________________________________Black spots of not smaller black dotthan .0.0.05 mm in size judgement______________________________________Nil/cm.sup.2 .circleincircle.1.about.3 spots/cm.sup.2 .largecircle.4.about.10 spots/cm.sup.2 .DELTA.Not less than 11 spots/cm.sup.2 X______________________________________
In the table, when a black-dot judgement was resulted to be .circleincircle. and .largecircle., the subject photoreceptor can be put to practical use; when it is resulted to be .DELTA., the subject photoreceptor may sometimes be impractical; and when it was proved to be .times., the subject photoreceptor cannot be practical.

As described above, when any electrophotographic photoreceptor relating to the invention is incorporated into a copier or printer and is then used repeatedly, every highly photoreceptive and excellent image can be provided without producing any image defect or image failure such as white-dots, black-dots, fog and density lowering.
Even when any electrophotographic photoreceptor relating to the invention is incorporated into a copier or printer and then used repeatedly, every excellent image can be provided with a reduced residual potential and without producing any image defect and image failure.
EXAMPLE 176
Next, an example different from the above-given examples, in which the invention was applied to an electroluminescence (EL), will be detailed.
Over to a transparent electrode (that was a layer made of indium and tin oxide) formed on a glass-made substrate, Exemplified Compound No.6 was so vacuum-evaporated as to serve as the electric charge injecting layer so that the thickness thereof could be 500 .ang.. Next, an 8-quinolinol A1 complex (A1q.sub.3) was vacuum-evaporated so as to serve as the organic fluorescent layer so that the thickness thereof could be 600 .ang.. Further, a magnesium/silver alloy was vacuum-evaporated thereon so as to serve as the negative electrode thereof.
When checking up the light emitting characteristics of the resulting thin organic EL element, a light emission of 0.04 mW/cm.sup.2 could be obtained at 4 mA/cm.sup.2. The emitted light was in yellowish green.
EXAMPLE 177
A thin organic EL element was prepared in the same manner as in Example 176, except that the electric-charge injecting layer used in Example 176 was replaced by Exemplified Compound No. (14) having 500 .ang. so as to serve as the electric-charge injecting layer thereof, (provided, therein the negative electrode was made of a magnesium/aluminium alloy). When checking up the resulting light emitting characteristics thereof, the resulting light emission of 0.05 mW/cm.sup.2 could be obtained at 5 mA/cm.sup.2. The emitted light was in yellowish green.
EXAMPLE 178
A thin organic EL element was prepared in the same manner as in Example 176, except that the electric-charge injecting layer used in Example 176 was replaced by Exemplified Compound No. [21] having 500 .ang. so as to serve as the electric-charge injecting layer thereof, (provided, therein the negative electrode was made of a magnesium/aluminium alloy). When checking up the resulting light emitting characteristics thereof, the resulting light emission of 0.06 mW/cm.sup.2 could be obtained at 6 mA/cm.sup.2. The emitted light was in yellowish green.
