Abstract:
An imaging method utilizing an imaging member containing a supporting substrate, a layer of a charge carrier injecting surface, a hole blocking layer, an optional adhesive layer, a layer of a charge carrier transport material, a layer of an charge carrier generating material, an optional charge trapping layer, a crossed linked silicone rubber, and an electrically insulating overcoating layer. The member is first charged with electrostatic charges of a first polarity, charged a second time with electrostatic charges of a polarity opposite to said first polarity in order to substantially neutralize the charges residing on the electrically insulating surface of the member and exposed to an imagewise pattern of activating electromagnetic radiation whereby an electrostatic latent image is formed. The electrostatic latent image may be developed to form a visible image which may be transferred to a receiver member. The imaging member may be reused after erasure and cleaning.

Abstract:
Aryldiamine charge transporting molecules for a charge transport layer of an imaging member have a higher mobility by increasing the number of phenyl groups between the nitrogen atoms of the aryldiamine. The aryldiamine has the formula(X-Ph)(Y-Ph)-N-(Ph)n-N-(Ph-Y)(Ph-X),wherein Ph represents a phenyl group and in which (Ph)n consists of ortho- and/or para-conjugated unsubstituted phenyl groups, X represents a hydrogen atom or an alkyl group having from 1 to about 20 carbon atoms, Y represents a hydrogen atom or an alkyl group having from 1 to about 20 carbon atoms, and n is an integer greater than 3. A charge transport layer is prepared by molecularly dispersing or dissolving the aryldiamine charge transporting molecule in a polymeric binder.
Abstract:
A composition is provided for coating a photoreceptor having a charge generating layer and a charge transport layer. The composition includes a hole transport material, a cross-linkable film forming binder having at least one functional group that is reactive with isocyanate, a blocked isocyanate cross-linking agent and a solvent having a boiling point equal to or below the deblocking temperature. The blocked isocyanate cross-linking agent is the reaction product of an isocyanate and a blocking agent, wherein the blocking agent has a boiling point temperature equal to or below a selected deblocking temperature to allow the isocyanate to form cross-links. The invention also provides an electrophotographic imaging member with an overcoat layer comprising a cross-linked film forming binder, an isocyanate compound, a hole transport material, and optionally a surface energy reducing agent. Processes for making the imaging members are also provided.
