Electrophotographic photoreceptor, drum cartridge employing the electrophotographic photoreceptor, and image-forming apparatus

摘要

The present invention provides an electrophotographic photoreceptor which has high light resistance, has high durability in exposure to oxidizing gases such as ozone and NO_x, is excellent in mechanical properties such as printing durability, wearing resistance, marring resistance, and slip properties in repetitions of use, and further has excellent electrical properties. Specifically, the present invention provides an electrophotographic photoreceptor having an electroconductive substrate and provided thereon at least a photosensitive layer having a charge generation material, a charge transport material, and a binder resin.
