Abstract
An image forming apparatus includes a first image bearing member and a second shiftable image bearing member. A first transferring member transfers a toner image formed on the first image bearing member to the second image bearing member at a first region. A second transferring member transfers a toner image formed on the second image bearing member to a transferring material at a second region. A first electrifier is provided downstream of the second region and upstream of the first region in a shifting direction of the second image bearing member. A second electrifier is provided downstream of the second region and upstream of the first electrifier in the shifting direction. A voltage applying unit applies a voltage to the first and second electrifiers to transfer toner adhered to the first and second electrifiers onto the second image bearing member.
