ABSTRACT:
A photoconductive member comprises a substrate and a layer constituted of an amorphous material containing Si and Ge and exhibiting photoconductivity, said layer having a layer region containing nitrogen ununiformly in the direction of layer thickness, the distribution concentration curve of nitrogen in the direction of layer thickness being smooth and the maximum distribution concentration being present in said layer.
An amorphous layer of Si containing at least one of oxygen and carbon may overlie the above mentioned layer.
