Abstract

Abstract A photoconductive member comprises a support for a photoconductive member, an interface layer comprising an amorphous material containing silicon atoms and nitrogen atoms as constituent atoms, 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, a first amorphous layer exhibiting photoconductivity and comprising an amorphous material containing at least one member selected from the group consisting of hydrogen atoms and halogen atoms as constituent atoms in a matrix of silicon atoms, and a second amorphous layer containing an amorphous material represented by any of the formulas: Si.sub.a C.sub.1-a (0.4<a<1) . . . (1) (Si.sub.b C.sub.1-b).sub.c H.sub.1-c (0.5<b<1, 0.6 ≦c<1) . . . (2) (Si.sub.d C.sub.1-d).sub.e X.sub.1-e (0.47<d<1, 0.8≦e<1) . . . (3) (Si.sub.f C.sub.1-f).sub.g (H+X).sub.1-g (0.47<f<1, 0.8≦g<1) . . . (4) wherein X represents a halogen atom.
