Patent ID: 7504187

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, the overcoat layer further comprising a low surface energy modified polycarbonate polymer, the polymer being selected from the group consisting of a modified Bisphenol A polycarbonate of poly(4,4′-isopropylidene diphenyl carbonate) having polydimethyl siloxane present in the polymer back bone in an amount of from about 2% to about 10% by weight of the total weight of the polymer and having the following formula (I): wherein x is an integer representing a number of repeating units of the polydimethyl siloxane present in an amount of from about 2% to about 10% by weight of the total weight of the polymer and, y and z are integers representing a number of repeating units, a modified Bisphenol Z polycarbonate of poly(4,4′-diphenyl-1,1′-cyclohexane carbonate) having polydimethyl siloxane present in the polymer back bone in an amount of from about 2% to about 10% by weight of the total weight of the polymer and having the following formula (II): wherein x is an integer representing a number of repeating units of the polydimethyl siloxane present in an amount of from about 2% to about 10% by weight of the total weight of the polymer and, y and z are integers representing a number of repeating units, a modified Bisphenol C polycarbonate of poly(4,4′-isopropylidene diphenyl carbonate) having polydimethyl siloxane present in the polymer back bone in an amount of from about 2% to about 10% by weight of the total weight of the polymer and having the following formula (III): wherein x is an integer representing a number of repeating units of the polydimethyl siloxane present in an amount of from about 2% to about 10% by weight of the total weight of the polymer and, y and z are integers representing a number of repeating units, a modified Bisphenol Z polycarbonate of poly(4,4′-diphenyl-1,1′-cyclohexane carbonate) having polydimethyl siloxane present in the polymer back bone in an amount of from about 2% to about 10% by weight of the total weight of the polymer and having the following formula (IV): wherein x is an integer representing a number of repeating units of the polydimethyl siloxane present in an amount of from about 2% to about 10% by weight of the total weight of the polymer and, y and z are integers representing a number of repeating units, and mixtures thereof.
