Abstract

An electrophotographic imaging member including a substrate, a charge generating layer, a charge transport layer including charge transporting molecules dispersed in a first polymer binder, and an overcoat layer including a triphenyl methane molecule dispersed in a second polymer binder, the second polymer binder being soluble in a solvent in which the first polymer binder is insoluble and the charge transport layer being substantialy free of any triphenyl methane molecules. The overcoat layer may also contain a charge transport molecule. The device may also include any suitable optional charge blocking, adhesive and other sub layers. This electrophotographic imaging member is fabricated by forming on a charge generating layer a first coating comprising charge transporting molecules dispersed in a solution of a first polymer binder dissolved in a first solvent, drying the coating to remove the solvent to form a substantially dry charge transport layer, forming on the charge transport layer a second coating comprising triphenyl methane molecules and charge transporting molecules dispersed in a solution of a second polymer binder dissolved in a second solvent, the first polymer binder being insoluble in the second solvent and the charge transport layer being substantialy free of any triphenyl methane molecules, and drying the second coating to remove the second solvent to form a substantially dry overcoat layer. This electrophotographic imaging member may be utilized in an electrophotographic imaging process.
