摘要： In an image forming apparatus a length of a transfer material in a conveying direction thereof is L.sub.p, a length of a toner image transferred onto an intermediate transfer belt in a shifting direction is L.sub.p ', a distance between a first transfer portion t.sub.1 and a second transfer portion t.sub.2 along the shifting direction of the intermediate transfer belt is L.sub.t1-t2 and a distance between the second transfer portion t.sub.2 and a fixing portion fix along the shifting direction of the transfer material is L.sub.t2-fix, so that the following relation is established:L.sub.t1-t2 >L.sub.p ' and L.sub.p >L.sub.t2-fix.After a first transfer is complete and before initiation of a second transfer, the speed of the intermediate transfer belt is decreased, so that, following to the second transfer process at a low speed, the toner image can be fixed onto the transfer material at a low speed. With this arrangement, the distance L.sub.t2-fix between the second transfer portion and the fixing portion is reduced to make the apparatus compact and the reduction of the through-put can be prevented while preventing poor fixing.
