Abstract
The image forming apparatus includes an endless and movable transfer material bearing belt, a transfer member, an opposing member and a belt guide member, wherein a conveyance direction of the transfer material in a first area is substantially the same as a conveyance direction of the transfer material in a second area, the first area corresponding to a nip area formed by the opposing member and the transfer member and the second area corresponding to an area in which the belt guide member bringing the transfer material bearing belt and the image bearing belt come into contact with each other. By the virtue of the present invention, a transfer material is restrained from scraping off the leading end of a toner image before the leading end of the toner image enters a transfer nip portion, while suppressing spattering of the toner image on the upstream of the transfer nip portion.
