    摘要： A process for fabricating an electrophotographic imaging member includingforming a charge generating layer,forming an undried charge transport layer coating by applying to the charge generating layer a solution selected from either or both the group consisting ofa solution including a charge transport molecule, a first film forming binder and at least a first solvent anda solution including a charge transporting polymer and at least a first solvent,forming an undried overcoat layer coating by applying to the undried charge transport layer coating an overcoat layer coating solution including a second film forming polymer and at least a second solvent, the charge transport molecule and first film forming polymer or either or both a charge transporting polymer being substantially insoluble in the second solvent and the second polymer being substantially insoluble in the first solvent,applying heat to both the undried charge transport layer coating and the undried overcoat layer coating to migrate the first solvent from the charge transport layer coating through the undried overcoat layer coating while maintaining the overcoat layer coating porous to migration of the first solvent through the overcoat layer coating until the charge transport layer is substantially dry,increasing the heat applied to the overcoat layer coating to form a substantially dry overcoat layer.

    摘要： 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.

    摘要： A flexible electrophotographic imaging member including a supporting substrate coated with at least one imaging layer including hole transporting material containing a hole transporting molecule dissolved or molecularly dispersed in a film forming binder and coated from a mixture of solvents including a low point boiling solvent and a small concentration of high boiling point solvent. Preferably, the flexible electrophotographic imaging member is free of an anticurl backing layer, the imaging member including a supporting substrate uncoated on one side and coated on the opposite side with at least a charge generating layer and a charge transport layer containing hole transporting material dissolved or molecularly dispersed in a film forming binder and coated from a mixture of solvents containing a low boiling point solvent and a small concentration of high boiling point solvent.
