ABSTRACT:
A photoconductive member is provided which has substrate for photoconductive member and a light-receiving layer having photoconductivity with 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 consisting of an amorphous material containing silicon atoms are successively provided from the aforesaid substrate side, said light-receiving layer containing carbon atoms together with a substance (C) for controlling conductivity in a distribution state such that, in said light-receiving layer, the maximum value C(PN).sub.max of the distribution concentration of said substance (c) in the layer thickness direction exists within said second layer region (S) and, in said second layer region (S), said substance (C) is distributed in greater amount on the side of said substrate.
