摘要:
The presently disclosed embodiments are directed to charging devices which produce a negative corona. The present embodiments pertain to the use of a positive charging device, such as a scorotron, after the erase lamp and before negative charging station in the xerographic cyclic to mitigate the undesirable changes in charge transport layer electrical properties that result from exposure to corona while negatively charging the photoreceptor during latent image formation.
摘要:
The presently disclosed embodiments are directed to charge transport layers useful in electrostatography. More particularly, the embodiments pertain to an improved imaging member having a charge transport layer comprising a top layer and a bottom layer, wherein the layers have varying concentrations of high quality N,N,N′N′-tetra(4-methylphenyl)-(1,1′-biphenyl)-4,4′-diamine to provide tunable discharge rate.

摘要:
An imaging member having an overcoat layer formed from a high viscosity overcoat composition. The viscosity of the overcoat composition is sufficient for reducing or preventing the diffusion of charge transport molecules into the overcoat layer. For example, in one embodiment the magnitude of diffusion of charge transport molecules is controlled by the viscosity of the overcoat composition used to form the overcoat layer. Other embodiments are also disclosed.
