Patent ID: 8084173

Claim:
An electrophotographic imaging member comprising: a flexible substrate with a conducting layer; at least one imaging layer positioned on a first side of the substrate; an anticurl back coating positioned on a second side of the substrate opposite to the at least one imaging layer, wherein the anticurl back coating has at least one layer and a thickness of from about 5 to about 80 microns and further comprises a low surface energy modified polycarbonate polymer having a weight average molecular weight of between about 20,000 and about 200,000, the polymer being formed and selected from the group consisting of: a modified Bisphenol C polycarbonate of poly(4,4′-isopropylidene di-(2-methylphenyl)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, and an adhesion promoter; and an optional overcoat layer on the at least one imaging layer.
