INDUSTRIAL APPLICATION FIELD The present invention relates to an electrophotographic photoreceptor, and more specifically,
The present invention relates to an electrophotographic photoreceptor having a photosensitive layer containing a specific azo pigment. Conventional technology Conventionally, inorganic photoconductive substances such as amorphous selenium, selenium alloys, cadmium sulfide, and zinc oxide, and organic photoconductive substances such as polyvinyl carbazole and polyvinyl carbazole derivatives have been used as electrophotographic photosensitive materials. is widely known. Compared to inorganic photoconductive materials, organic photoconductive materials are
It has the advantage of being excellent in terms of transparency, film-forming properties, flexibility, manufacturability, etc. Problems to be Solved by the Invention Despite having such many advantages, organic photoconductive materials have not been used in electrophotographic photoreceptors because inorganic photoconductors have poor sensitivity and durability. It was to be inferior. Therefore, the present invention was made in view of the above-mentioned drawbacks when using an organic photoconductive substance, and its purpose is to provide an electrophotographic photoreceptor with high sensitivity and high durability.

結果は、第1表に示す通りである。[Table] The above disazo compounds used in the present invention are:
For example, the corresponding diamine is tetrazotized by a conventional method and coupled with a coupler represented by the general formula H-Cp in the presence of an alkali, or the tetrazonium salt of the corresponding diamine is converted into a borofluoride salt or a zinc chloride double salt. It can be synthesized by isolating the compound as a form and then coupling it with the above coupler in a suitable solvent (eg, N,N-dimethylformamide, dimethyl sulfoxide, etc.) in the presence of an alkali. In the present invention, the bisazo compound is contained in the photosensitive layer provided on the conductive support,
The photosensitive layer may have a single layer structure or a laminated structure in which a charge generation layer and a charge transport layer are functionally separated. The electrophotographic photoreceptor of the present invention includes, for example, (1) a photosensitive layer formed by dispersing a bisazo compound in a binder resin containing a charge transport substance on a conductive support; (2) a conductive support; A photosensitive layer comprising a bisazo compound and a charge transfer complex dispersed in a binder resin is provided on a support, and (3) a charge generation layer containing a bisazo compound and a charge transport substance are provided on a conductive support. It can be roughly divided into those provided with a charge transport layer containing. The conductive support in the electrophotographic photosensitive plate of the present invention may be a metal plate made of aluminum, nickel, chromium, stainless steel, etc., a metal drum, or a plastic film provided with a metal foil and a thin film of metal or other conductive substance. Paper or plastic film coated with or impregnated with a conductivity imparting agent is used. In the present invention, when the bisazo compound is dispersed in the binder resin in the photosensitive layer formed on the conductive support, the bisazo compound is
Hereinafter, it is preferably dispersed as fine particles with a particle size of 0.3 μ or less, and the amount of blending is determined relative to the photosensitive layer.
It is desirable that the content be 20% to 90% by weight. As the binder resin, polystyrene, silicone resin, polycarbonate, acrylic resin, methacrylic resin, polyester, vinyl polymer such as polyvinyl butyral, cellulose such as cellulose ester, cellulose ether, alkyd resin, etc. can be used. .

In the present invention, it is preferable that the photosensitive layer has a laminated structure because the sensitivity of the electrophotographic photoreceptor is high and the residual potential is low. In this case, the charge generation layer may be formed by dispersing the bisazo compound in the binder resin as described above, but it may also be formed by sublimation or vapor deposition of the bisazo compound. Further, either a charge generation layer or a charge transport layer may be provided as an upper layer; when a charge generation layer is provided as an upper layer, the electrophotographic photoreceptor is of a positively charged type, and when a charge transport layer is provided as an upper layer It can be used as a negatively charged type. In the electrophotographic photoreceptor of the present invention, an adhesive layer may be provided between the photosensitive layer and the conductive support.
The adhesive layer is made of commonly used synthetic resin such as polyester, and is usually formed to have a thickness of about 0.5 to 5 μm. Examples Hereinafter, the present invention will be explained using examples. Example 1 1 part by weight of polyvinyl butyral resin (trade name: BLX Sekisui Chemical Co., Ltd.) was dissolved in 40 parts by weight of cyclohexanone, 3 parts by weight of Exemplary Compound No. 1 was mixed therein, and then mixed in a paint shaker.
