Abstract:
A process for forming a photosensitive imaging member comprising:(a) 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 defined by R.sub.a ranging from about 0.05 to about 0.7 micrometer, R.sub.t ranging from about 0.5 to about 6 micrometers, R.sub.pm ranging from about 0.2 to about 2 micrometers, W.sub.t ranging from about 0.1 to about 1 micrometer, P.sub.t ranging from about 0.8 to about 6 micrometers 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, and(b) depositing onto the substrate surface (i) a charge generating layer and a charge transport layer in any order, or (ii) a single photoconductive layer.
