Abstract: An image forming apparatus includes a transfer roller, a fuser, a chute, a drive source, a reciprocating mechanism, and a controller. The transfer roller transfers toner to a sheet. The fuser fixes toner on the sheet. The chute is located upstream from the fuser in a sheet conveying direction. The chute is configured to convey the sheet toward the fuser. The chute is movable between a first position and a second position. The reciprocating mechanism reciprocates by drive force from the drive source and moves the chute between the first position and the second position. The controller executes: a first mode of actuating the drive source when conveying one sheet; and a second mode of not actuating the drive source when conveying one sheet. The controller switches between the first mode and the second mode in a middle of a print job.
