    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: 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.
