ABSTRACT:
An image forming apparatus includes a movable belt; a first image carrying member for carrying a toner image; a first transfer member for electrostatically transferring a toner image onto the belt or a recording material carried on the belt; a second image carrying member; and a second transfer member for electrostatically transferring the toner image onto the belt or the recording material carried. The first transfer member contacts the belt and has a first end portion at a first position. The second transfer member contacts the belt and has a second end portion, at a second position, closer to the first end portion than the second contact portion perpendicular to a movement direction of the belt. The first position deviates from the second position so that first and second areas of the belt subjected to electric discharge first do not overlap.
