Abstract
An apparatus for forming toner images on both sides of a sheet includes a first transfer device which transfers a toner image from a rotatable image forming body onto a rotatable intermediate transfer member or onto the first side of a sheet; a second transfer device which transfers a toner image from the rotatable intermediate transfer member onto the second side of the sheet; and a fixing device which fixes the toner image on the first side of the sheet and the toner image on the second side of the sheet simultaneously. The sheet is conveyed to the first transfer device and to the second transfer device by the rotatable intermediate transfer member, is separated at a separating section from the rotatable intermediate transfer member, and is brought to the fixing device. The second transfer device is located between the first transfer device and the separating section, and a conductive member is located opposite the second transfer device.
