Abstract: A persistent conductivity-type electrophotographic recording member comprising a nonconductive layer and a photoconductive layer disposed on one surface of the nonconductive layer, wherein the photoconductive layer comprises a photosensitive material substantially uniformly dispersed in a binder which consists essentially of a copolymer of styrene with at least one alkyl acrylate, the alkyl group of which comprises from four to twelve carbon atoms. The acid value of such copolymers is typically preferably below about 2, and more preferably below about 1.

Abstract: A photocoductive film comprising at least one photosensitive material dispersed in a resinous binder is supersensitized and the dark decay rate thereof reduced by adding an effective amount of an organic acid having at least one carboxyl functional group and at least one hydroxyl functional group to the coating mixture from which the film is formed. The organic acid is an independent component of the coating mixture and is substantially not copolymerized with the binder resin.
