ABSTRACT:
It is desirable to reduce disturbance of an unfixed toner image by suppressing vibration of the trailing end of a recording medium, and to thereby stabilize the quality of a formed image. In a first control time period based on the leading edge of the recording medium as a reference, a driving unit is controlled in accordance with detection of a loop. On the other hand, in a control time period after the first control time period, a target speed is determined from a drive speed of the driving unit in the first control time period, and the driving unit is controlled by the determined target speed.
