1. An image forming apparatus comprising: a first shaft which holds a roll of a recording medium that is wound in a roll shape; a platen drum which supports a part of the recording medium which continues to the roll of the recording medium held by the first shaft; a pair of rollers which nip the recording medium between the first shaft and the platen drum; and a control unit which applies a tension to the recording medium, wherein the control unit selectively executes a first mode in which the tension between the first shaft and the platen drum is applied, and a second mode in which the tension between the first shaft and the pair of rollers is released while applying the tension between the pair of rollers and the platen drum, tension between the pair of rollers and the platen drum in the second mode being less than a tension for image forming and greater than zero.
