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.

摘要:
The presently disclosed embodiments relate in general to electrophotographic imaging members, such as layered photoreceptor structures, and processes for making and using the same. More particularly, the embodiments pertain to the incorporation of a liquid compound having a high boiling point into the charge transport layer such that an anticurl back coating is no longer needed for reduction or elimination of photoreceptor upward curling.
摘要:
An imaging member comprising a barrier or under-layer intermediate a photogenerating layer and charge transport layer to reduce charge deficiency spots. The barrier under-layer comprises a film forming polymer binder selected from a conductive polymer binder, a non-conductive polymer binder, or mixtures thereof. Optionally, the barrier layer can include a small amount of a charge transport material.

A photoconductive imaging member containing a photogenerating layer, a charge transport layer, or a plurality of charge transport layers, and which charge transport, especially the top charge transport layer contains a vinyl containing organic compound.
摘要:
A photoconductor comprising a substrate, an undercoat layer, a photogenerating layer and a charge transport layer is described. The undercoat layer is disposed on the substrate and comprises a metal oxide, and a mixture of a phenolic resin and a cyclohexanecarboxylate.

摘要:
The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrostatographic, including digital, apparatuses. Embodiments pertain to an improved electrostatographic imaging member comprising an interfacial layer further comprising an opaque semi-crystalline polyester resin that is also a hot-melt adhesive to prevent light transmission to the substrate and thus significantly reduce “plywood effect,” a print quality defect.
