Abstract
A process for manufacturing an electrophotographic photosensitive member is disclosed in which a source gas is decomposed by the use of a high-frequency power in a rector to deposit sequentially on a conductive substrate i) a photoconductive layer comprised of an amorphous material composed chiefly of silicon atoms and ii) a surface layer comprised of an amorphous material composed chiefly of carbon atoms and containing hydrogen atoms. The process has the steps of forming the photoconductive layer in a first reactor, and forming the surface layer in a second reactor. This process can produce an electrophotographic photosensitive member having an a-Si photoconductive layer and a-C:H surface layer or a-C:H(Si) surface layer in a good efficiency and at a low cost. Also disclosed is an electrophotographic photosensitive member manufacturing apparatus which carries out the process.
