摘要： The presently disclosed embodiments relate in general to electrophotographic imaging members, such as layered photoreceptor structural simplification, and material reformulation for making and using the same. More particularly, the embodiments pertain to the incorporation of a plasticizer into the charge transport layer such that an anticurl back coating is no longer needed for reduction or elimination of the layered photoreceptor curling.

摘要： The presently disclosed embodiments relate generally to the formulation of an anticurl back coating layer that renders imaging apparatus flexible members and components their desirable flatness, for use in electrostatographic, including digital apparatuses. More particularly, the embodiments pertain to an imaging member comprising an anticurl back coating layer formulated to comprise a polymer blend of an anti-static polymer and a low surface energy A-B diblock copolymer polymer and an adhesion promoter. The embodiments provide an imaging member belt with the anticurl back coating that is electrically conductive and also substantially reduces its surface contact friction to help suppress/eliminate tribo-electrical charge build-up at the backside of the imaging member belt under normal machine imaging member belt operational conditions in the field.
