Abstract: Provided is an imaging member comprising a substrate, an undercoat layer (UCL), a charge generation layer, a charge transport layer, and an optional overcoat layer. The undercoat layer is formed from a single-phase UCL coating formulation comprising an organic titanate, a polymer containing active hydrogen, and an aminosilane. The UCL formulation has improved properties such as stability, processing convenience, and longer pot life etc. The UCL formulation can be used to manufacture an imaging member such as photoreceptor with improved properties such as stable, thick UCL coating, resistance to electrical failure, and PIDC independency on UCL thickness etc.

Abstract: A photoreceptor and method of forming the same is disclosed. A photoreceptor includes a substrate, an undercoat layer, and an imaging layer. The undercoat layer comprises a single, non-porous anodized aluminum layer that has an impedance of less than about 50 Kohm. The single, non-porous anodized aluminum layer may be used as the undercoat layer alone, or may be part of a multi-layered undercoat layer system that includes additional layers of other undercoat materials. The use of the non-porous anodized aluminum layer provides the photoreceptor with an extended effective life.
