Abstract:
1. An imaging member comprising: an electrically conductive substrate or a substrate comprising an electrically conductive layer; a photogenerating layer; and, a charge transport layer deposited on the photogenerating layer, wherein the charge transport layer comprises a first charge transport layer comprised of a charge transport component and a film forming polymer binder, and thereover and in contact with the first charge transport layer, a plurality of additional charge transport layers, each comprised of a charge transport component and a film forming polymer binder, wherein the amount of charge transport component in said layers of the charge transport layer is the greatest in said first charge transport layer and progressively decreases to the uppermost layer of the additional charge transport layers; and wherein the charge transport layer further comprises a stabilizing hindered phenol, wherein the concentration of the hindered phenol increases from the first charge transport layer to the uppermost layer of the additional charge transport layers.
