| 摘要 |
An electrophotographic photoreceptor comprising a conductive substrate having thereon a photosensitive layer is disclosed, said photosensitive layer containing, as a binder resin, a polycarbonate resin comprising at least a repeating unit represented by formula (I): <IMAGE> (I) wherein R1, R2, R3, and R4 each represent a hydrogen atom, a halogen atom, an alkyl group having from 1 to 5 carbon atoms, a cycloalkyl group having from 5 to 7 carbon atoms or a phenyl group; and R5 and R6 are taken together to form a 5- to 8-membered carbonaceous ring substituted with at least two alkyl groups each having from 1 to 5 carbon atoms. The photoreceptor has high mechanical durability and satisfactory surface smoothness, resistance against reduction in image quality and sensitivity, and stability against environmental change and repeated use.
