Abstract:
1. 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; an overcoat layer disposed on the at least one charge transport layer; and an anticurl back coating positioned on a second side of the substrate opposite to the charge generating layer and the at least one charge transport layer, wherein the overcoat layer and the anticurl back coating includes an adhesion promoter, a bisphenol type polycarbonate having a weight average molecular weight of between 20,000 and 200,000 and being selected from the group consisting of a bisphenol A polycarbonate of poly(4,4′-isopropylidene diphenyl) carbonate having the following formula (A): wherein n indicates each respective degree of polymerization, a modified bisphenol A polycarbonate of poly(4,4′-isopropylidene diphenyl) carbonate having the following formula (B): wherein m indicates each respective degree of polymerization, a bisphenol Z polycarbonate of poly(4,4′-diphenyl-1,1′-cyclohexane) carbonate having the following formula (C): wherein n indicates each respective degree of polymerization, a modified bisphenol Z polycarbonate of poly(4,4′-diphenyl-1,1′-cyclohexane) carbonate having the following formula (D): wherein p indicates each respective degree of polymerization, a phthalate-bisphenol A polycarbonate having the following formula (E): wherein w is an integer from about 1 to about 20 and n is the degree of polymerization, and mixtures thereof, an ultra high weight average molecular weight bisphenol type polycarbonate of formulas (A) to (E), which is greater than 200,000, and a slip agent.
