  • Publication number: 20180275597
    Abstract: An image forming apparatus which transfers, onto paper, a toner image formed on a belt-shaped image carrier including an elastic layer on a surface thereof, and forms an image includes a rigid blade which cleans the surface of the image carrier in contact with the image carrier which has transferred the toner image onto the paper; a roller which is upstream of the rigid blade in a rotation direction of the image carrier, and cleans the surface of the image carrier upstream of the rigid blade by coming in contact with the image carrier which has transferred the toner image onto the paper; a rigid blade holder which holds the rigid blade; and a roller holder which holds the roller. The rigid blade holder and the roller holder are installed with a gap therebetween.

  • Publication number: 20170139371
    Abstract: A cleaning apparatus which cleans an image carrier that has an elastic layer after a toner image formed on the image carrier is transferred onto a transfer object, the cleaning apparatus including: a cleaning blade which contacts the image carrier and removes a residue attached to the image carrier; a change section which changes a cleaning condition of cleaning by the cleaning blade; and a hardware processor which controls the change section to change the cleaning condition in accordance with deterioration of the image carrier.

  • Patent number: 9575438
    Abstract: An image forming device includes: an image carrier on which a toner image is formed; and a cleaning blade which removes a residual material on the image carrier after the toner image is transferred to a transferred body, wherein the image carrier includes an elastic layer, the cleaning blade is a metallic plate spring, and a tip end of the cleaning blade is pressed against the image carrier by restoring force of the plate spring.

  • Patent number: 9417595
    Abstract: An image forming apparatus transfers a toner image formed on an image carrier having a moving surface onto a transfer object, and includes: a cleaning member that performs a removal operation on residues remaining on the image carrier after transfer of the toner image; and a brush member that has bristles including original yarns with uneven surfaces formed by microparticles adhering to and coating the original yarns, and comes into contact with the image carrier, on a downstream side relative to the cleaning member in a movement direction of the surface of the image carrier, to remove part of the residues that remains unremoved on the image carrier even after the removal operation performed by the cleaning member.
