    摘要: A secondary transfer facing roller includes a roller part that has a through-hole penetrating in a rotary shaft line direction at a rotation center position, and a penetrating shaft member penetrating the through-hole of the roller part and spinning the roller part on a surface of the penetrating shaft member. Eccentric cams are fixed to both end regions that are not located in the roller part, so as to rotate integrally with the penetrating shaft member. A position regulating cam and an abutting roller form a gap between the intermediate transfer belt and the secondary transfer roller immediately before a transfer sheet enters a transfer nip part. While the gap is formed, current flows between the intermediate transfer belt and the secondary transfer roller via the position regulating cam and the abutting roller.

    摘要: A transfer device includes a plurality of rollers, a rotatable intermediate transfer belt wound around and stretched between the rollers, a transfer member disposed in the inner loop of the belt and facing an image bearing member of an image forming apparatus disposed at an outer circumference of the belt, to transfer an image formed onto the surface of the image bearing member when contacting the intermediate transfer belt, and a position adjuster to adjust the position of the intermediate transfer belt at different positions relative to the image bearing member. The positions include a contact state in which the intermediate transfer belt applied with a predetermined tension contacts the image bearing member, a first separation state in which the tensioned intermediate transfer belt separates from the image bearing member, and a second separation state in which the intermediate transfer belt separates further away from the image bearing member.

    摘要: To provide an image forming apparatus capable of increasing the life of a rotating cam while preventing the occurrence of a shock jitter and transfer failure. The image forming apparatus is configured to execute a forced movement process for rotating the rotating cam to forcibly move a secondary transfer roller against a biasing force of a bias coil spring at a pre-entry timing prior to the entry of the front edge of a recording sheet into a secondary transfer position, and a pressure intensifying process for rotating the rotating cam to increase transfer pressure at a timing immediately after the entry of the front edge of the recording sheet into the secondary transfer position. As the forced movement process, the image forming apparatus executes, alternately, a first forced movement process for normally driving and rotating the rotating cam, and a second forced movement process for inversely driving and rotating the rotating cam, at a predetermined timing.
