An image forming apparatus according to an embodiment includes an image forming unit, a heating unit, a fan, a guide, and a control unit. The image forming unit forms an image on a recording medium. The heating unit is disposed on a downstream side of the image forming unit in a transport direction of the recording medium. The heating unit is driven with at least two temperatures, a first temperature and a second temperature lower than the first temperature. The fan generates wind. The guide guides the wind generated from the fan to the heating unit. The control unit controls the fan and the guide when the control unit controls the heating unit by switching between driving the heating unit at the first temperature and at the second temperature.
