    摘要： A single-layered electrophotographic photoreceptor has a single-layered structure that includes a charge generating material, a charge transfer material, and a binder resin on a substrate. In one embodiment, the charge generating material is Y form titanyloxy phthalocyanine, and the binder resin is polyethylene terephthalate polymer. The single-layered electrophotographic photoreceptor has excellent stability, electrical characteristics, sensitivity and durability, and may be installed in a cartridge or on a drum of an image forming apparatus.

    摘要： A double-layered positively-charged organic photoreceptor t does not suffer from contamination caused by charge transport compounds that dissolve out during coating of a charge generating layer, and in which the charge generating layer and a charge transport layer have suitable interfacial properties for effective charge transfer. The composition that forms a charge transport layer on an electroconductive support contains a first charge transport compound that is soluble in an acetate solvent, a second charge transport compound that is insoluble in an acetate solvent, a binder resin, and an organic solvent. The method of manufacturing the photoreceptor includes: coating a surface of an electroconductive support with the charge transport layer forming composition and drying the surface to form a charge transport layer; and coating a surface of the charge transport layer with a charge generating layer forming composition and drying the surface to form a charge generating layer.
