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.
