    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.
