An image forming apparatus includes a control unit that applies a tension to a recording medium in a first region between a rotational shaft and a driving roller using a torque applied to the rotational shaft and the driving roller, and applies a tension to the recording medium in a second region where a support member supports the recording medium using a torque applied to the driving roller and a holding unit. The control unit selectively executes an image forming mode where the head is caused to execute image forming by applying a tension to the recording medium in the second region while applying a tension to the recording medium in the first region, and a medium detaching mode where the tension in the first region is released when the recording medium is stopped, while applying a tension for detaching a medium to the recording medium in the second region.
