ABSTRACT:
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): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 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 R.sub.5 and R.sub.6 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.
