PROBLEM TO BE SOLVED: To obtain an excellent image even when a transfer nip, a transfer material releasing position and a transfer material conveying part start point position are arranged in virtual almost triangle shape when performing transfer in a state where transfer material is gripped. SOLUTION: An image on an intermediate transfer belt 8 is transferred to the transfer material 20 gripped by a gripper 17 of a secondary transfer roller 14 at a secondary transfer nip 13a, and the transfer material 20 is conveyed by a transfer material conveying part 25. Moving speed of a transfer material conveying belt 25a when starting conveyance of the transfer material 20 is controlled to be higher than moving speed of the intermediate transfer belt 8. The terminal positionζof the secondary transfer nip, the transfer material releasing positionεwhich is arranged vertically upper on the side of a transfer material moving direction than the position of the secondary transfer nip, and the transfer material conveying part start point positionηwhich is arranged vertically upper on the side in the transfer material moving direction than the transfer material releasing positionεand where a leading edge of the transfer material 20 abuts on the transfer material conveying part 25 first are arranged in the virtual almost triangle shape.
