ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE HAVING ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND ELECTROPHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a electrophotographic photoreceptor free from the absorption of monochromatic light even when the photoreceptor is used for an electrophotographic device provided with an exposure means having monochromatic light source of 400-410 nm wavelength and having high sensitivity, high mechanical strength of wear resistance/scratch resistance and stable repeatability and to provide a process cartridge having the electrophotographic photoreceptor and the electrophotographic device. SOLUTION: In the electrophotographic photoreceptor having a photosensitive layer on a support, the surface is exposed by the monochromatic light source of 400-410nm wavelength and the photosensitive layer contains a charge producing material and a high-molecular charge transfer material having a specific repeating structural unit.
