Abstract
A photoconductive member comprising a support for photoconductive member and an amorphous layer exhibiting photoconductivity comprising an amorphous material containing silicon atoms as a matrix is characterized in that said amorphous layer has a first layer region containing, as constituent atoms, oxygen atoms in a distribution which is nonuniform and continuous in the direction of the layer thickness and a second layer region containing, as constituent atoms, the atoms (A) belonging to group III or group V of the periodic table in a distribution which is continuous in the direction of the layer thickness, said second layer existing internally beneath the surface of said amorphous layer.
