Zusammenfassung:PROBLEM TO BE SOLVED: To prevent an image defect even when bending stress of a transfer material is large.SOLUTION: An eccentric cam 80 for varying a distance V from the inside of an intermediate transfer belt 20 to a sheet conveyance chute 70 by a control unit 90 is arranged between a tacking position T and a sheet outlet 70a of the sheet conveyance chute 70 for conveying a sheet P to the tacking position T, and on the upstream side of a secondary transfer roll 31 and upstream side of the tacking position T of the sheet P to the intermediate transfer belt 20. When a rear end part of the sheet P collides with the intermediate transfer belt 20 due to restoration of a curvature posture, the impact is mitigated.
