摘要:
Embodiments pertain to a novel imaging member, namely, an electrostatic latent image generating member that can generate an electrostatic latent image digitally without using a raster output scanner (ROS), photoreceptor and charger. The imaging member facilitates the charge injection process between an organic conjugated polymer and N,N′-diphenyl-N,N′bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′diamine charge transport layer.

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 conductive carbon nanotubes dispersion in a polymer blend comprising three film-forming thermoplastic polymers to: (a) render electrical conductivity effect for tribo-electrical charge elimination (b) impart static dissipation capability, and (c) provide surface energy lowering effect for contact friction reduction to ease imaging member belt drive as well as cutting tribo-electrical charge build-up under normal imaging member belt operational conditions in the field.
摘要:
The exemplary embodiments disclosed herein incorporate transistor heating technology to create micro-heater arrays as the digital heating element for various marking applications. The transistor heaters are typically fabricated either on a thin flexible substrate or on an amorphous silicon drum and embedded below the working surface. Matrix drive methods may be used to address each individual micro-heater and deliver heat to selected surface areas. Depending on different marking applications, the digital heating element may be used to selectively tune the wettability of thermo-sensitive coating, selectively change ink rheology, selectively remove liquid from the surface, selectively fuse/fix toner/ink on the paper.

The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrostatographic, including digital, apparatuses. More particularly, the embodiments pertain to an improved electrostatographic imaging member incorporating a thermoplastic material pre-compounded to impart conductivity to the anti-curl back coating layer and may also contain an adhesion promoter which provides a conductively and optically anti-curl back coating layer. The conductive anti-curl back coating of the present disclosure may be formulated to have a single layer, dual layers, or triple layers.
