    摘要: An image forming apparatus includes a photoconductive element including a conductive support rotatably supported and a charge injection layer and a surface protection layer sequentially laminated on the conductive support. A charger includes a conductive body for injecting, when a preselected voltage is applied thereto, a charge in the charge injection layer in contact with the surface protection layer. A writing unit exposes the charged surface of the photoconductive element imagewise to thereby locally vary the potential deposited on the photoconductive element and electrostatically form a latent image. A developing unit develops the latent image to thereby produce a corresponding toner image. The toner image is transferred from the photoconductive element to a recording medium. Assuming that the charge injection layer has a thickness of D micrometers, and that the potential deposited on the surface of the photoconductive element by the conductive member is V volts in absolute value, then a ratio V/D is confined in a preselected range that does not contaminate the background of the photoconductive element.

    摘要: A method for electrostatically charging the surface of a photoconductive insulative layer which is formed by dispersing an inorganic n-type photoconductive powder in a binder, which is primarily a vinyl chloride-vinyl acetate copolymer, which comprises rubbing the insulative layer with a friction material so as to produce a negative charge on the surface of the insulative layer. Representative photoconductors, such as ZnO, and friction materials, such as a cotton velvet cloth, are set out in the specification. A modification of the process entails producing the friction by rubbing the insulative layer while a highly insulative liquid is maintained on its surface.

    摘要: An image forming apparatus includes a photoconductive element including a conductive support rotatably supported and a charge injection layer and a surface protection layer sequentially laminated on the conductive support. A charger includes a conductive body for injecting, when a preselected voltage is applied thereto, a charge in the charge injection layer in contact with the surface protection layer. A writing unit exposes the charged surface of the photoconductive element imagewise to thereby locally vary the potential deposited on the photoconductive element and electrostatically form a latent image. A developing unit develops the latent image to thereby produce a corresponding toner image. The toner image is transferred from the photoconductive element to a recording medium. Assuming that the charge injection layer has a thickness of D micrometers, and that the potential deposited on the surface of the photoconductive element by the conductive member is V volts in absolute value, then a ratio V/D is confined in a preselected range that does not contaminate the background of the photoconductive element.
