| 1. 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.
