Surface treatment method without external power source

摘要

There is disclosed a process for forming a photosensitive imaging member including positioning a substrate and an electrode in an electrolytic solution to form a galvanic cell and electrochemically graining the substrate surface in the absence of an external power source to provide a substrate surface roughness sufficient to substantially suppress the formation of a pattern of light and dark interference fringes upon exposure of the photosensitive imaging member to a light source.
