Abstract
An image forming apparatus includes an image forming portion, a reverse roller pair, a revering motor. A controller controls rotation of the reverse motor in a first feeding mode for the sheet with a first length and in a second feeding mode for the sheet with a second length shorter than the first length. The controller executes a first acceleration control in which the reverse motor rotating in the first rotational direction is accelerated from a predetermined speed to a first target speed faster than the predetermined speed after a rear end of the sheet passes through the image forming portion in the first feeding mode, and said controller executes a second acceleration control in which the reverse motor rotating in the first rotational direction is accelerated to a second target speed slower than the first target speed after the rear end of the sheet passes through the image forming portion in the second feeding mode.
