  • Publication number: 20110158722
    Abstract: A cleaning apparatus is provided with a cleaning roller that is positioned so as to be in contact with a photosensitive drum, and with a toner layer thickness regulating member that regulates the thickness of a toner layer adhering to the surface of this cleaning roller. The toner layer thickness regulating member is formed by a toner layer thickness regulating roller that rotates in contact with the cleaning roller.

  • Patent number: 7599652
    Abstract: An image forming apparatus comprises: a revolving image bearing member on which a toner image is formed; a transfer member that is provided at a position facing the surface of the image bearing member and transferring the toner image electrostatically on a transfer sheet traveling between the image bearing member and the transfer member; a static charge eliminator generating an electric field for discharging the electric charge on the transfer sheet for separation of the transfer sheet carrying the transferred toner image from the image bearing member; and a conductive member that is provided between the static charge eliminator and the transfer member.

  • Publication number: 20090239165
    Abstract: An image forming apparatus is provided with an image forming unit including an amorphous silicon photoconductor. The amorphous silicon photoconductor includes a base and a photosensitive layer provided on the base. The photosensitive layer includes a highly resistive layer, a charge-injection inhibition layer, a photoconductive layer and a surface protecting layer successively laminated on the base. The thickness of the highly resistive layer is in the range of 1 ?m to 4 ?m. The thickness of the photosensitive layer is in the range of 15 ?m to 25 ?m and the absolute value of a solid light potential of the photosensitive layer is in the range of 20 to 100 V.

  • Publication number: 20070086801
    Abstract: In an image forming apparatus, a control section 41 adjusts the surface potential of a photoconductor or the developing potential of a developer carrying member based on the detection result of a surface potential sensor 44, and performs first correction whereby, relative to the reference value of the applied bias of a charger 2 or the developing bias of the developer carrying member in a developing unit 4 as observed during potential adjustment, the applied bias or the developing bias is varied so as to keep constant the potential difference between the surface potential of the photoconductor and the developing potential of the developer carrying member during image formation. The control section also performs second correction whereby the applied bias or the developing bias is restored to the reference value over a predetermined period after the completion of continuous image formation.
