Abstract

Abstract A photoconductive member comprises a support for photoconductive member, an interface layer comprising an amorphous material represented by any of the formulas: Si.sub.a N.sub.1-a (0.57<a<1) (1) (Si.sub.b N.sub.1-b).sub.c H.sub.1-c (0.6<b<1, 0.65≦c<1) (2) (Si.sub.d N.sub.1-d).sub.e (X, H).sub.1-e (0.6<d<1, 0.8≦e<1) (3) (wherein X represents a halogen atom), a rectifying layer comprising an amorphous material containing atoms (A) belonging to the group III or the group V of the periodic table as constituent atoms in a matrix of silicon atoms, and an amorphous layer exhibiting photoconductivity comprising an amorphous material containing at least one of hydrogen atoms and halogen atoms as constituent atoms in a matrix of silicon atoms.
