Abstract:
1. An imaging member comprising: an electrically conductive substrate or a substrate comprising an electrically conductive layer; a charge generating layer; and a single charge transport layer deposited on the charge generating layer; wherein the charge transport layer comprises a lower surface in contact with the charge generating layer and an upper surface; wherein the charge transport layer comprises a film forming polymer binder, a charge transport compound, and a stabilizing hindered phenol dispersed therein; wherein the concentration of the charge transport compound in the charge transport layer decreases from the lower surface to the upper surface; wherein the concentration of the charge transport compound in a region near the upper surface is about 40% to about 60% less than the concentration of the charge transport compound in a region near the lower surface; and wherein the concentration of the hindered phenol increases from the lower surface to the upper surface of the charge transport layer.
