Abstract

A charge transport layer for an imaging member comprising a dual charge transport layer and wherein the charge transport layers comprise a photogenerating layer; (1) a first charge transport layer comprised of a charge transport component and a resin binder; and thereover and in contact with the first layer; (2) a second top charge transport layer comprised of a charge transport component, a resin binder and a hindered phenol dopant. The charge transport layer exhibits, excellent electrical performance, outstanding print quality and reduces the diffusion of the anti-oxidant into the charge generator layer.
