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.
