Abstract
An image forming apparatus includes an intermediate transfer member, an image forming device for forming a toner image on the intermediate transfer member, a charging device for charging residual toner remaining on the intermediate transfer member after the toner image formed by the image forming device and located on the intermediate transfer member is electrostatically transferred onto a transfer material. The residual toner charged by the charging device and remaining on the intermediate transfer member is electrostatically transferred onto the image forming device. After the toner image is transferred from the intermediate transfer member to a first side of the transfer material, a toner image can be transferred from the intermediate transfer member to a second side of the transfer material opposite to the first side, and a control device for controlling voltage to be impressed to the charging device in dependence upon whether the toner image was transferred from the intermediate transfer member to the first side of the transfer material or the toner image was transferred from the intermediate transfer member to the second side of the transfer material.
