    摘要: A transfer-separation device includes an intermediate transfer unit, a secondary transfer roller, a repulsive roller, a transfer unit, and a charge-eliminating/separating member. The secondary transfer roller and the repulsive roller form a nip through which the intermediate transfer unit and a recording medium pass. The transfer unit applies a bias voltage of a polarity identical to that of a toner image to the repulsive roller to secondarily transfer the toner image onto the recording medium. The charge-eliminating/separating member separates the recording medium from the intermediate transfer unit by removing charge therefrom. The volume resistance of the repulsive roller is greater than that of the secondary transfer roller. The surface resistance of the secondary transfer roller is equal to or greater than 106.5 ohm.

    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.
