摘要:
Release layers, and particularly low surface tension aqueous solutions, such as fountain solutions, which function as release layers. These release layers are integrated into copying and printing machines, such as xerographic machines, multifunctional devices, color systems, and the like, wherein the release layers are specifically incorporated onto a hydrophilic roll material for contact leveling of UV curable gel inks.

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.

In accordance with the invention, there are xerographic photoreceptors, image forming apparatus, and methods of forming an image on image. The xerographic photoreceptor can include a substrate and a conductive ground plane having an optical transparency disposed over the substrate, the conductive ground plane including a carbon nanotube layer, such that machine cycling of the xerographic photoreceptor can produce less than approximately a 10% change in the optical transparency of the conductive ground plane after about 100,000 or more machine cycles. The xerographic photoreceptor can also include a photosensitive layer disposed over the conductive ground plane, wherein the photosensitive layer can include a charge generator material and a charge transport material.
