Abstract
In an image formation apparatus for sequentially forming toner images on an image carrier and transferring the toner images onto a transfer material on a transfer material support member which is moved in an endless manner, when the transfer material is brought into contact with the image carrier other than in a transfer process, the surface of the image carrier is maintained at the same polarity as that of toner transferred to the transfer material. Thus, toner image transferred to the transfer material can be prevented from being offset onto the image carrier.
