Patent ID: 7517624

Claim:
An electrostatographic imaging member comprising: a substrate having a first and second side, wherein the substrate has a conductive surface; an imaging layer disposed on the first side of the substrate, wherein the imaging layer comprises: a charge generating layer and, a charge transport layer disposed on the charge generating layer comprising a charge transport compound and a polymeric binder formed from a monomer selected from the group consisting of modified Bisphenol A polycarbonate poly(4,4′-isopropylidene diphenyl carbonate), modified Bisphenol Z polycarbonate poly (4,4′-diphenyl-1-1′cyclohexane carbonate), and mixtures thereof, wherein the charge transport layer has a bottom layer, one or more intermediate layers, and an outermost layer and further wherein weight percent of the polymeric binder to the charge transport compound in the one or more intermediate layers increases in the direction of the bottom layer to the outermost layer, the weight percent of the outermost layer being greater than the weight percent of every other intermediate layer; and an anti-curl backing layer disposed on the second side of the substrate, wherein the anti-curl backing layer comprises an adhesive promoter.
