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.
