ABSTRACT:
A photoconductive member comprises a substrate for photoconductive member and a light receiving layer provided on said substrate having a layer constitution in which a first layer region (G) comprising an amorphous material containing germanium atoms and a second layer region (S) exhibiting photoconductivity comprising an amorphous material containing silicon atoms are successively provided from the substrate side, said light receiving layer containing a substance for controlling conductivity (C) in a distributed state such that, in said light receiving layer, the maximum value of the content of said substance (C) in the layer thickness direction exists within said second layer region (S) or at the interface with said first layer region (G) and, in said second layer region (S), said substance (C) is distributed in greater amount on the side of said substrate.
