Abstract:
A method for manufacturing an electrophotographic photosensitive member comprising a photoconductive film of non-monocrystalline material comprising silicon on a cylindrical aluminum substrate having an inner surface, which comprises in sequence:(a) cleaning an outer surface of the cylindrical aluminum substrate with water containing dissolved carbon dioxide such that a conductivity of the water is from 2 &mgr;S/cm to 40 &mgr;S/cm; (b) fitting the inner surface of the cylindrical aluminum substrate over a repeatedly usable substrate holder, the substrate holder having at least (i) a cylindrical outer surface for receiving the cylindrical aluminum substrate, (ii) a hollow cylindrical core comprising a metal, wherein a surface only of the hollow portion of the core is ceramic having a ten points average roughness (Rz) between 5 and 200 &mgr;m and the metal is in contact with the ceramic; and (c) forming by chemical vapor deposition (CVD) on the outer surface of the cylindrical aluminum substrate the photoconductive film comprising the non-monocrystalline material comprising silicon atoms thereby forming the electrophotographic photosensitive member.
