Abstract

A method for forming a low surface energy coating for electrophotographic photosensitive body substrates does not require performing a physical surface reforming treatment such as corona discharge, plasma treatment, and the like. The process comprises: forming on the substrate at least one polysiloxane coating material, (B), that has a water contact angle greater than the water contact angle of the substrate; and thereafter forming an outermost surface coating material, (A), on top of coating material (B). The water contact angle of coating material (B) is smaller than the water contact angle of coating material (A). Coating material (A) comprises finely divided silica and a resin of the formula RSiO.sub.3/2, wherein not less than 1 mol % and not more than 80 mol % of the R groups are fluorohydrocarbon groups of 3 to 12 carbon atoms.
