Abstract
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: SiaC1-a(0.4<a<1) (1) (SibC1-b)cH1-c(0.5<b<1, 0.6</=c<1) (2) (SidC1-d)eX1-e(0.47<d<1, 0.8</=e<1) (3) (SifC1-f)g(H+X)1-g(0.47<f<1, 0.8</=g<1) (4) (wherein X represents a halogen atom).
