Abstract

An image forming apparatus includes a first roller pair including a first roller and a second roller, a first driving unit, a second roller pair, a second driving unit, an image forming unit, and a control unit configured to execute a first mode and a second mode. The second mode includes (1) a first processing, (2) a second processing, and (3) a third processing of controlling the first driving unit such that the rotational speed of the first roller pair becomes faster than the second rotational speed. The first mode includes (1) a fourth processing, (2) a fifth processing, and (3) a sixth processing of controlling the first driving unit such that the rotational speed of the first roller pair is decelerated from the first rotational speed to equal to or less than the second rotational speed.
