1. An image forming apparatus configured to form an image on a medium and write data to a wireless tag attached to the medium, comprising:
a fixing device including a heater; and
a controller configured to:
upon detection of a first wireless tag attached to a medium, determine a first distance between an upstream end of the medium and a first region of the medium to which the first wireless tag is attached based on a strength of a signal received from the first wireless tag, and determine a first timing at which the first region begins to pass the fixing device based on the first distance and a second timing at which the first region completely passes the fixing device based on the first distance, and
control the fixing device to heat the medium at a first temperature before the first timing and after the second timing and at a second temperature that is lower than the first temperature between the first and second timings.
