    摘要： An electrophotographic printing machine has a photoreceptive member. The photoreceptive member is charged and then exposed with a light image representation to form a latent image. An electric field, less than that required to re-charge the photoreceptive member, is applied to the latent image to increase the rate of discharge of the exposed portions of the latent image. The latent image is then developed.

    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 process is disclosed for ascertaining electrical discharge properties of an electrophotographic imaging member including the steps of (a) providing at least one electrophotographic imaging member comprising an electrically conductive layer and at least one photoconductive layer, (b) contacting the surface of the electrophotographic imaging member with a substantially transparent electrode and applying an electric potential or an electric current to form an electric field across the photoconductive layer, (c) terminating the applying of the electric potential or the electric current, (d) exposing the photoconductive layer to activating radiation to discharge the electrophotographic imaging member, (e) repeating steps (b), (c) and (d), and (f) measuring the potential across the photoconductive layer during steps (b), (c) and (d) as a function of time by means of an electrostatic meter coupled to the electrode. Also, disclosed is apparatus for ascertaining electrical discharge properties of an electrophotographic imaging member including (a) means to support an electrophotographic imaging member comprising an electrically conductive layer and at least one photoconductive layer, (b) means for applying an electric potential or electric current to a substantially transparent electrode on the electrophotographic imaging member to form an electric field across the photoconductive layer, (c) means for terminating the applying of the electric potential or the electric current, (d) an electrostatic voltmeter probe coupled to the means for applying an electric current to the electrode, (e) means for exposing the photoconductive layer through the substantially transparent electrode to activating radiation to discharge the electrophotographic imaging member to a predetermined level, and (f) means for exposing the photoconductive layer to activating radiation to fully discharge the electrophotographic imaging member.
