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： An image forming apparatus is operable to form an image on a recording medium. An image carrier is adapted such that a toner image is formed thereon by developing an electrostatic latent image. An intermediate transfer member is adapted such that the toner image is primarily transferred thereto. In a transfer device, a roller member is adapted to come in contact with the intermediate transfer member. A first bias voltage applier is operable to provide a transfer voltage, thereby applying a first bias voltage between the roller member and the intermediate transfer member to secondarily transfer the toner image onto the recording medium in order to obtain the image. A charge eliminator is disposed in the vicinity of the roller member. A second bias voltage applier is operable to apply a second bias voltage to the charge eliminator to eliminate charges on the recording medium which has been subjected to the application of the first bias voltage. A controller is operable to vary the second bias voltage in accordance with a deviation amount of the first bias voltage.
