Patent ID: 7217483

Claim:
An electrophotographic photoreceptor comprising an electroconductive substrate and having provided thereon at least a photosensitive layer comprising a charge generation material, a charge transport material, and a binder resin, wherein a polyarylate resin is selected as the binder resin and the photosensitive layer and/or a layer formed on the outer side of the layer contains a light-absorbing compound which is a compound whose absorbance (value for a tetrahydrofuran solution thereof) in the range of from 420 nm to 520 nm has at least one maximal absorbance value and which has compatibility with the layer containing the compound, and wherein said charge generation material is photoconductive material selected from the group consisting of an inorganic photoconductive material and an organic photoconductive material, wherein said inorganic photoconductive material is selected from the group consisting of selenium, alloys of selenium, and amorphous silicon, wherein said organic photoconductive material is selected from the group consisting of phthalocyanine pigments, guinacridone pigments, indigo pigments, perylene pigments, polycyclic quinone pigments, anthanthrone pigments, and benzimidazole pigments, with the proviso that where said photoconductive material is an organic photoconductive material and said organic photoconductive material is a phthalocyanine pigment, said phthalocyanine pigment is a metal-bound phthalocyanine pigment, with the further proviso that when said metal-bound phthalocyanine pigment is a titanyl phthalocyanine, said titanyl phthalocyanine is crystalline.
