A recording-medium positioning device includes a gate, a roller pair, a roller-pair shift unit, a recording-medium detector, and a drive control device. The gate is disposed at an upstream side of a fixing device in a conveyance direction of a recording medium. The roller pair includes two roller members disposed at an upstream side of the gate. The roller-pair shift unit moves the roller pair in accordance with a first position of the recording medium in the conveyance direction to shift the recording medium in a width direction perpendicular to the conveyance direction. The recording-medium detector is disposed between the fixing device and the gate to detect a second position of the recording medium in the width direction. The drive control device moves the recording medium to a reference position by driving the roller-pair shift unit in accordance with the second position and cyclically shifts the reference position.
