Process for producing electrophotographic photosensitive member

Claim 1

Process for preparing an electrophotographic photosensitive member for use in an electrophotographic process which includes applying a primary voltage of a certain polarity to an insulating layer of the photosensitive member, applying or discharging a secondary voltage of a polarity opposite to that of the primary charge simultaneously with imagewise exposure by radiation energy and applying a blanket radiation to produce electrostatic latent images on the surface of the insulating layer, comprising the steps of (a) coating a dispersion of photoconductive CdS particles in a resin binder dissolved in a solvent for the resin binder onto a substrate, (b) removing the solvent thereby forming a photoconductive film composed of said photoconductive particles dispersed in said resin binder, (c) forming an insulating layer on the photoconductive film, wherein said resin binder has a glass transition temperature Tg and (d) conducting said steps (a) and (b) at a temperature T wherein the value (Tg-T) is from (-35° C.) to (+40° C.) and wherein said resin binder has a volume resistivity of not lower than 10 11 ohm.cm.
