The present invention relates to an electrophotographic photoreceptor, and more particularly to an electrophotographic photoreceptor containing a novel organic photoconductive substance comprising an azine compound. Electrophotography has already been covered by Carlson's U.S. Patent No.
As revealed in No. 2297691, its electrical resistance changes depending on the amount of radiation received during image exposure.
A photoconductive material consisting of a support coated with an insulating substance is used in the dark. The photoconductive material is generally first given a uniform surface charge in the dark after dark adaptation for a suitable period of time. The material is then imagewise exposed to a pattern of radiation that has the effect of reducing the surface charge depending on the relative energy contained in different parts of the radiation pattern. The surface charge or electrostatic latent image thus left on the surface of the photoconductive material layer (photosensitive layer) then becomes a visible image when that surface is contacted with a suitable electrometric indicator, ie, toner.
Toner, whether contained in an insulating liquid or in a dry carrier, can be deposited on the surface of the photosensitive layer depending on the charge pattern. The deposited display material can be fixed by known means such as heat, pressure, and solvent vapor. The electrostatic latent image can also be transferred to a second support (eg, paper, film, etc.). It is likewise possible to transfer the electrostatic latent image to a second support and develop it there. Electrophotography is one of the image forming methods in which images are formed in this manner. The basic characteristics required of the photoreceptor in such electrophotography are (1) ability to be charged to an appropriate potential in the dark, (2) low dissipation of charge in the dark, (3) For example, the charge can be quickly dissipated by light irradiation. It is true that conventionally used inorganic photoconductive materials such as selenium, cadmium sulfide, and zinc oxide have many advantages, but also have various disadvantages. For example, selenium, which is currently widely used, fully satisfies the conditions (1) to (3) above, but the manufacturing conditions are difficult, the manufacturing cost is high, it is not flexible, and it cannot be processed into a belt shape. It also has disadvantages, such as being difficult to handle and being sensitive to heat and mechanical shock, requiring careful handling. Cadmium sulfide and acertic oxide are used as photoreceptors by being dispersed in resin as a binder, but they have mechanical drawbacks such as smoothness, hardness, tensile strength, and abrasion resistance, so they cannot be used as is. and cannot be used. In recent years, in order to eliminate the drawbacks of these inorganic photoconductive materials, electrophotographic photoreceptors using various organic photoconductive materials have been proposed, and some of them are in practical use. For example, photoreceptors made of poly-N-vinylcarbazole and 2,4,7-trinitrofluoren-9-one (US Pat. No. 3,484,237), poly-N-
- Vinylcarbazole sensitized with pyrylium salt dyes (Japanese Patent Publication No. 48-25658), photoreceptors whose main component is a eutectic complex consisting of a dye and a resin (Japanese Patent Application Laid-open No. 10735-1987), etc. It is. Although electrophotographic photoreceptors using these organic photoconductors have improved mechanical properties and flexibility to some extent than those using the inorganic photoconductors, they generally have low photosensitivity and are not suitable for repeated use. First, it did not fully satisfy the requirements for an electrophotographic photoreceptor. Furthermore, a highly sensitive electrophotographic photoreceptor has been proposed that combines a substance that generates electric charges when exposed to light (called a charge-generating substance) and a substance that can transport the generated charges (called a charge-transporting substance). has been done. For example, US Pat. No. 3,791,826 discloses a photoreceptor in which a charge transport layer is provided on a charge generating layer.
No. 3,573,906 discloses a photoreceptor in which a charge generation layer is provided on a charge transport layer.
No. 3,764,315 describes a photoreceptor having a photosensitive layer in which a charge generating material is dispersed in a charge transporting material. Examples of charge transporting agents used in this charge generation layer include those disclosed in JP-A-54-59143 (U.S. Pat. No. 4,150,987).
hydrazone compounds described in U.S. Patent No.
Pyrazoline compounds described in 3180729, U.S. Pat.
Although triarylamine described in No. 3567450 can be mentioned, it has not been possible to obtain an electrophotographic photoreceptor having sufficient performance in terms of sensitivity. Regarding azine compounds, Japanese Patent Publication No. 42-5587
In JP-A No. 58-1989, it was also published as a photoconductive compound.
No. 132240 describes it as a charge transporting compound. Also, in Japanese Patent Application Laid-Open No. 57-90634,
Symmetrical ketazine compounds synthesized from 4'-di(N-disubstituted amino)benzophenones have been shown to have photoconductivity and charge transport properties. However, even when the azine compounds described in these patents are used as organic photoconductors or charge transport materials, it has not been possible to obtain electrophotographic photoreceptors with sufficient sensitivity. Furthermore, among the azine compounds described in these patents, the use of ketazine compounds in particular has the disadvantage that crystals of the ketazine compounds precipitate on the surface of the photoreceptor produced. An object of the present invention is to provide a new electrophotographic photoreceptor that solves the above-mentioned problems. Another object of the invention is to provide new organic photoconductive materials. Another object of the present invention is to provide a compound suitable as a charge transport material for use in a photosensitive layer having a laminated structure of a charge generation layer and a charge transport layer. As a result of extensive research, the present inventors found that among azine compounds, substituted ketones other than 4,4'-di(N-disubstituted amino)benzophenone and It has been discovered that an asymmetric azine compound synthesized from two different substituted aldehydes has particularly excellent performance both as a photoconductive compound and as a charge transport compound. This object of the present invention is achieved by an electrophotographic photoreceptor having a layer containing an azine compound represented by the following general formula (1). In the formula, R 1 , R 2 , R 3 , and R 4 may be the same or different, and each represents a linear or branched chain having 1 to 1 carbon atoms such as methyl, ethyl, propyl, butyl, etc.
12 alkyl groups, aralkyl groups such as benzyl and phenethyl, aryl groups such as phenyl and naphthyl, or residues that form a cyclic amino group together with nitrogen atoms such as pyrrolidino, piperidino and morpholino. In addition, these alkyl groups, aralkyl groups, and aryl groups may have a substituent, and examples of the substituent include alkyl groups such as methyl and ethyl;
In addition to alkoxy having 1 to 8 carbon atoms such as methoxy and ethoxy, halogen atoms such as chlorine and bromine, hydroxyl groups, cyano groups, etc. can be mentioned. R 5 is hydrogen, substituted or unsubstituted, having 1 to 12 carbon atoms,
Alkyl group, aralkyl group, unsubstituted or carbon number 1
-8 represents an aryl group containing an alkyl group, an alkoxy group, a halogen atom, a hydroxyl group, or a cyano group as a substituent. R 6 has 1 to 8 carbon atoms,

ã枬å®ãããçµæã第ïŒè¡šã«ç€ºãã[Table] As is clear from Example 1 and Comparative Examples 1 and 2, 4,4'-di(N-disubstituted amino) according to the present invention
Asymmetric azine-based compounds synthesized from benzophenone have better sensitivity and better charging characteristics after recycling than azine-based compounds synthesized from carbonyl compounds other than 4,4'-(N-disubstituted amino)benzophenone. ing. This indicates that the compound according to the present invention is different from the comparative compound (A-
Since it has one more N-disubstituted amino group than 1) and (A-2), the highest occupied level of the compound becomes higher, resulting in a higher hole injection efficiency from the charge generation layer to the charge transport layer. I think it's because he's getting better. Furthermore, as is clear from Example 1 and Comparative Example 3, the symmetric azine compound synthesized from 4,4'-di(N-disubstituted amino)benzophenone has a higher sensitivity than the asymmetric azine compound according to the present invention. In addition to its low solubility, it has the disadvantage that crystals tend to precipitate on the surface of the photoreceptor. Example 5 1 part by weight of azine compound (1) according to the present invention, 4-
0.01 part of [4-(N-2-chloroethyl, N-2-cyanoethyl)styryl]-2,6-di-t-butylthiopyrylium fluoroborate and 1.5 parts of polycarbonate (Lexan 121) were dissolved in methylene chloride.
A coating solution was prepared by dissolving in a mixed solvent of 40 parts of ethylene chloride and 80 parts of ethylene chloride. This coating solution was coated with a wire bar onto a transparent conductive film on which soot-doped indium oxide was deposited on the surface of a polyethylene terephthalate film, and dried to obtain a photoreceptor having a photosensitive layer with a film thickness of 5 ÎŒm. This photoreceptor was manufactured using the same equipment as in Example 1.
When charged to 250v and measured E50 , it was 10luxã»sec. Examples 6 to 8 Photoreceptors were prepared in the same manner as in Example 5, except that azine compound (1) was replaced with (2), (4), and (8), respectively, and the sensitivity was measured. The results are shown in Table 3.

ãã§ããã[Table] Crystals were deposited on the photoreceptor surface of the photoreceptor prepared in Comparative Example 6 after being left at room temperature for one week. Example 9 1 part of bisazo pigment with the following structure, azine compound
(3) 5 parts, and polycarbonate (Lexan 121)
5 parts of methylene chloride were added to 95 parts of methylene chloride, and the mixture was shaken for 1 hour in a paint shaker to prepare a coating solution. This coating solution was applied with a wire bar to a conductive support made of a polyethylene terephthalate film on which aluminum was vapor-deposited, and dried to obtain a single-layer photoreceptor having a photosensitive layer with a thickness of 10 Όm. Using the same apparatus as in Example 1, this electrophotographic photoreceptor was charged to +450V by +5kV corona discharge and exposed to tungsten light. The half-reduction exposure (E 50 ) was measured and found to be 9 lux·sec. Even if the two steps of charging and exposure are repeated 1000 times,
E 50 remained almost unchanged. Example 10 1 part of the bisazo pigment used in Example 9, 2 parts of the azine compound, and 6 parts of m-cresol formaldehyde resin were added to 30 parts of ethylene glycol monomethyl ether, and this was ground in a ball mill.
The coating solution was mixed and applied to a grained, anodized and sealed aluminum plate approximately 0.25 mm thick using a wire round rod.
It was dried at 50°C for 10 minutes and for 1 day to prepare a sample with a thickness of about 6 Όm. Next, corona discharge was applied to this sample in a dark place so that the surface potential became 500 V, and after exposing the negative image to tungsten light (100 lux seconds), Mitsubishi Diafax Master LOM-ED toner (Mitsubishi Paper When reversal development was performed using a printing press (manufactured by Co., Ltd.), a very clear positive image could be obtained on the original printing plate.
This printing original plate was immersed for 1 minute in a 10-fold diluted etching solution DP-1 (manufactured by Fuji Photo Film Co., Ltd.; sodium silicate aqueous solution), and the photosensitive layer was removed from the areas to which toner was not attached (non-image areas). was dissolved and removed. As a result, the pigment in the non-image area was easily removed together with the binder, and a printing plate with a clear image could be formed.
