Abstract

PURPOSE: To prevent a positional deviation of an image in the first color and prevent overlapped color misregister, by providing a rotatable body which presses a sheet material on a feeding belt against the feeding belt and is rotated following the movement of the belt, prior to forming an image.
CONSTITUTION: A transfer material S supplied from a transfer material supplying part 2 and placed on a feeding belt 15 is clamped by a supplying roller pair 17, is supplied to a nipping part between the belt 15 which has stopped moving and a pressure roller 19, and the material S is caused to slacken at the nipping part. With the belt 15 started moving, the roller 19 is rotated following the movement of the belt 15 while pressing the material S against the belt 15. The transfer material S is fed under the condition where the slack is maintained between the roller 19 and the supplying roller pair 17. Alternatively, the transfer material S is fed while maintaining a slack which is formed by setting the circumferential velocity of the roller pair 17 to be slightly higher than the velocity of the belt 15. Accordingly, propagation of wow and flutter to a transferring part 11a for the first color is restrained by the slack, so that the transferring part 11a is not adversely affected by the wow and flutter at all.
