<p>A transfer-separation device includes an intermediate transfer unit (11), a secondary transfer roller (22), a repulsive roller (16), a transfer unit, and a charge-eliminating/separating member (23). The secondary transfer roller (22) and the repulsive roller (16) form a nip through which the intermediate transfer unit (11) 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 (16) to secondarily transfer the toner image onto the recording medium. The charge-eliminating/separating member (23) separates the recording medium from the intermediate transfer unit (11) by removing charge therefrom. The volume resistance of the repulsive roller (16) is greater than that of the secondary transfer roller (22). The surface resistance of the secondary transfer roller (22) is equal to or greater than 10 6.5 ohm.</p> |
