ELECTROPHOTOGRAPHIC PHOTORECEPTOR, CARTRIDGE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that reduces a surface potential and a residual potential at the initial stage and after repeated use of the electrophotographic photoreceptor to an exposure energy during writing of latent images and prevents the occurrence of image defects, and to provide a cartridge and an image forming apparatus.SOLUTION: There is provided an electrophotographic photoreceptor that has an undercoat layer and a photosensitive layer on a conductive support, where the undercoat layer contains an electron absorbing compound; the electron absorbing compound has a LUMO energy level of -2.50 to -3.20 eV and a polarizability of 27 to 43Å; and the photosensitive layer contains a polycarbonate resin.
