Abstract
A layered photoreceptor is composed of a substrate, an extrinsic pigment layer that has been sensitized disposed over the substrate, and a charge transport polymer in contact with the pigment layer. A method for producing a photoreceptor comprises depositing a layer of sensitizing electron donor material in a polymer binder on a substrate. An extrinsic pigment layer is deposited on the layer of sensitizing electron donor material. A charge transport layer is deposited on the pigment layer.
