Abstract
A process for the preparation of a photosensitive body surface coating material comprises hydrolytically condensing an alkoxysilane in a mixed solvent comprising an alcohol and water in the presence of finely divided silica. A polysiloxane resin is produced by heat curing the silane after its hydrolytic condensation. The polysiloxane resin has the formula: R.sup.1 SiO.sub.3/2, and R.sup.1 comprises fluorohydrocarbon groups. The photosensitive body surface coating material is not detrimental to the functionality required of the electrophotographic photosensitive bodies, has superior optical uniformity, has low surface energy, and has superior surface hardness.
