おり、電荷発生層と電荷輸送層に機能分離した感光層に
おける電荷発生物質として光導電性のジスアゾ顔料を用
いた電子写真感光体が知られている。[Prior Art] Electrophotographic photoreceptors containing inorganic photoconductors such as selenium, cadmium sulfide, and zinc oxide in the photosensitive layer are well known. On the other hand, organic photoconductive polymers such as poly-N-vinylcarbazole and polyvinylanthracene, low-molecular organic photoconductors such as carbazole, anthracene, pyrazolines, oxadiazoles, and hydrazones, phthalocyanine pigments, azo pigments, indigo dye,
Organic photoconductors such as thioindigo dyes and methine squaric acid dyes have been developed. Further, for example, US Pat. No. 4,123,270, US Pat. No. 4,24761
As disclosed in U.S. Pat. No. 4, U.S. Pat. No. 4,251,613, U.S. Pat. Electrophotographic photoreceptors using disazo pigments are known.

、感度と繰返し使用に対する耐久性に難点があるため、
これまで実用化されているものはごく僅かである。An electrophotographic photoreceptor using such an organic photoconductor can be produced using a coating method using dip coating by appropriately selecting a binder, making it possible to provide an extremely highly productive and inexpensive photoreceptor. Although it has the advantage of being able to select a clearing pigment that exhibits photoconductivity in the wavelength range, it has drawbacks in terms of sensitivity and durability against repeated use.
Only a few have been put into practical use so far.

電子写真感光体を提供することにある。[Problems to be Solved by the Invention] An object of the present invention is to provide an electrophotographic photoreceptor containing a novel organic photoconductor in its photosensitive layer.
