    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： An electrophotographic imaging member including

    at least one photographic imaging layer and
    a partially electrically conductive overcoat layer including

    finely divided charge injection enabling particles dispersed in
    a charge transporting continuous matrix including a cross linked polyamide, charge transport molecules and oxidized charge transport molecules, the continuous matrix being formed from a solution selected from the group including

    a first solution including

    crosslinkable alcohol soluble polyamide containing methoxy methyl groups attached to amide nitrogen atoms,
    an acid having a pK a of less than about 3,
    a cross linking agent selected from the group comprising a formaldehyde generating cross linking agent, an alkoxylated cross linking agent, a methylolamine cross linking agent and mixtures thereof,
    a dihydroxy arylamine, and
    a liquid selected from the group including alcohol solvents, diluent and mixtures thereof,

    a second solution including

    crosslinkable alcohol soluble polyamide free of methoxy methyl groups attached to amide nitrogen atoms,
    an acid having a pK a of less than about 3,
    an alkoxylated cross linking agent, a methylolamine cross linking agent and mixtures thereof,
    a dihydroxy arylamine, and
    a liquid selected from the group including alcohol solvents, diluent and mixtures thereof.




    The electrophotographic imaging process is also disclosed.
