  • Publication number: 20120076559
    Abstract: A cleaner includes a cleaning member having a distal end in contact with an image carrier so as to remove developer attached to the image carrier, a cleaning container that stores the removed developer, a cleaning support body including a cleaning support portion extending from the distal end to a proximal end of the cleaning member so as to support the proximal end of the cleaning member, a bent portion bent from the cleaning support portion, and a supported portion supported by the cleaning container, a vibration-damping body in contact with an end of the bent portion opposite the cleaning support portion so as to regulate vibration of the cleaning support body, and a vibration-damping-body fixing member supported by the cleaning container and having a clamp portion that clamps the vibration-damping body between the vibration-damping-body fixing member and the end of the bent portion.
