    摘要： A process for producing an electrophotographic photoreceptor comprising the steps of forming a photoconductive layer on a conductive substrate in a reaction chamber, and after the photoconductive layer is formed, forming a surface protection layer on the photoconductive layer by introducing into the reaction chamber a gaseous mixture comprising (i) a first component, fluorohydrocarbon gas, and (ii) a second component silicon, hydride gas, or a hydrocarbon gas and/or hydrogen gas and decomposing the gaseous mixture by glow discharge, wherein the surface protection layer thus formed comprises amorphous silicon carbide when the second component is a silicon hydride gas or amorphous carbon when the second component is a hydrocarbon gas and/or hydrogen gas. The surface protection layer exhibits sufficient hardness to protect the photoconductive layer from frictional scratches and other related damage.

    摘要： An electrophotographic photoreceptor comprising a photoconductive layer, a first surface layer and a second surface layer formed in sequence on a support, said photoconductive layer being substantially composed of amorphous silicon, and each of said first and second surface layers being substantially composed of nitrogen-doped amorphous silicon, the concentration of nitrogen atoms in the second surface layer being higher than that in the first surface layer. The photoconductive layer is doped with atoms of an element of group III, or in at least a part of the photoconductive layer doped with germanium atoms in place of the element of group III.
