Abstract

A photoconductive member, comprises a support for a photoconductive member, a first amorphous layer exhibiting photoconductivity comprising an amorphous material containing silicon atoms as a martix, said first amorphous layer having a first layer region containing oxygen atoms in a distribution which is continuous and ununiform in the direction of layer thickness and a second layer region containing atoms belonging to the group III of the periodic table as constituent atoms in a distribution which is continuous and ununiform in the direction of layer thickness, and a second amorphous layer comprising an amorphous material represented by any of the following formulae: EQU Si.sub.a C.sub.1-a (0.4<a<1) (1) EQU (Si.sub.b C.sub.1-b).sub.c H.sub.1-c (0.5<b<1, 0.6.ltoreq.c<1) (2) EQU (Si.sub.d C.sub.1-d).sub.e X.sub.1-e (0.47<d<1, 0.8.ltoreq.e<1) (3) EQU (Si.sub.f C.sub.1-f).sub.g (H+X).sub.1-g (0.47<f<1, 0.8.ltoreq.g<1) (4) (wherein X represents a halogen atom).
