PROBLEM TO BE SOLVED: To prevent both image displacement and image tip end part transfer failure that are caused when a tip end of a recording body enters the transfer nip without damaging an image carrier, in an image forming apparatus for transferring a toner image on the image carrier with a transfer electric field formed in the transfer nip. SOLUTION: A position regulating cam 78 and an abutting roller 72 that function as gap forming means form a gap between the intermediate transfer belt 10 and the secondary transfer roller 23 immediately before a transfer sheet enters a transfer nip part. While the gap is formed, current that is induced by transfer voltage applied by a transfer voltage applying means 75 flows between the intermediate transfer belt 10 and the secondary transfer roller 23 via the position regulating cam 78 and the abutting roller 72.
