Patent ID: 7998646

Claim:
An electrophotographic imaging member comprising: a substrate; a charge generating layer disposed on the substrate; at least one charge transport layer disposed on the charge generating layer; and an overcoat layer disposed on the charge transport layer, wherein the overcoat layer comprises a low surface energy modified polycarbonate polymer having a molecular weight of between about 20,000 and about 200,000, the polymer being formed and selected from the group consisting of modified Bisphenol A polycarbonate of poly(4,4′-isopropylidene diphenyl carbonate) having a small fraction of polydimethyl siloxane in the polymer back bone and having the following formula (I): wherein x is an integer between about 40 and about 50 while y and z are integers representing a number of the respective repeating units, a modified Bisphenol Z polycarbonate of poly(4,4′-diphenyl-1,1′-cyclohexane carbonate) having a small fraction of polydimethyl siloxane in the polymer back bone and having the following formula (II): wherein x is an integer between about 40 and about 50 while y and z are integers representing a number of the respective repeating units, a modified Bisphenol C polycarbonate derived from the modification of poly(4,4′-isopropylidene diphenyl carbonate) having a small fraction of polydimethyl siloxane in the polymer back bone and having the following formula (III): wherein x is an integer between about 40 and about 50 while y and z are integers representing a number of the respective repeating units, a modification of the modified Bisphenol Z polycarbonate of poly(4,4′-diphenyl-1,1′-cyclohexane carbonate) having a small fraction of polydimethyl siloxane in the polymer back bone and having the following formula (IV): wherein x is an integer between about 40 and about 50 while y and z are integers representing a number of the respective repeating units, and mixtures thereof; wherein the overcoat layer further comprises a charge transport compound, an ozone suppression agent and a slip agent; and an anticurl back coating positioned on a second side of the substrate opposite to the charge generating and the charge transport layers.
