ABSTRACT:
A process for producing an electrophotographic photosensitive member comprising the steps of depositing a non-single crystal material composed basically of silicon atoms, on a cylindrical substrate in a deposition chamber, thereafter once taking the substrate with film out of the deposition chamber, then returning it to the deposition chamber, and thereafter again depositing thereon a non-single-crystal material composed basically of carbon atoms. In another embodiment, the process comprises the steps of depositing on a cylindrical substrate a photoconductive layer formed of a non-single crystal material, subjecting to surface processing the deposited film having protrusions present at its surface, and depositing on the processed surface a surface protective layer formed of a non-single-crystal material. Also disclosed is the electrophotographic photosensitive member thus obtained, and an electrophotographic apparatus having that member.
