Abstract
A photoreceptor comprising a charge transport layer doped with a polyarylate polymer is provided. A charge transport layer is doped with about 0.1 to about 10.0% by weight, solids basis, of a polyarylate polymer, such as for example Ardel. Charge transport layers doped with a polyarylate polymer exhibit improved electrical performance in terms of lower Vr and VBG values.
