Abstract

A photoconductive member comprising a support for photoconductive member, a photoconductive layer constituted of an amorphous material comprising silicon atom as a matrix and a barrier layer between said support and said photoconductive layer, said barrier layer having a double-layer structure of a first barrier layer constituted of an amorphous material comprising silicon atom as a matrix and containing impurities which control the property of conductivity and a second barrier layer constituted of an electrically insulating material different from said amorphous material constituting said first barrier layer.
