ABSTRACT:
Since a barrier layer of an electrophotographic photosensitive member interposed between a photoconductive layer and conductive substrate is formed of a first BN layer of high resistivity laminated with a second .mu.c-Si layer having a rectifying function, the charging capacity is elevated and the residual potential is reduced. A photoconductive layer prepared from a-Si has a high sensitivity to light rays having a broad range of wavelengths. A surface layer prepared from .mu.c-Si containing nitrogen N, carbon C or oxygen O has a high charge-retaining capability.
