Abstract

An electrophotographic imaging member including a supporting substrate, an electrically conductive layer including at least a partially crosslinked polymer having a backbone derived from an alkyl acrylamidoglycolate alkyl ether, a charge blocking layer including a polymer having a backbone also derived from an alkyl acrylamidoglycolate alkyl ether and at least one photoconductive layer. Preferably, the backbone derived from an alkyl acrylamidoglycolate alkyl ether is a copolymer of methyl acrylamidoglycolate methyl ether and a vinyl hydroxy ester or vinyl hydroxy amide. This imaging member may be prepared by a coating process and employed in an electrostatographic imaging process.
