Abstract
An image forming apparatus includes an image forming unit to form an image on a sheet while conveying the sheet at an image forming speed, a discharge roller pair to discharge the sheet, a conveyance roller pair to convey the sheet from the image forming unit to the discharge roller pair, and a control unit to control a motor to switch a speed of the conveyance roller pair and the discharge roller pair between a first speed corresponding to the image forming speed and a second speed higher than the first speed. In first control, the speed is switched from the second to the first speed at timing at which a trailing end of the sheet reaches a first position. In second control, the speed is switched from the second to the first speed at timing at which a leading end of a subsequent sheet reaches a second position.
