Abstract
A fixing device includes a fixing member, a temperature measurement sensor, a movement mechanism, a movement time calculation section, a movement position calculation section, and a temperature control section. The movement mechanism moves the temperature measurement sensor to scan non-heated regions and a heated region along a width direction of the fixing member. The movement time calculation section obtains an arrival time on the basis of a temperature change measured by the temperature measurement sensor due to movement of the temperature measurement sensor. The movement position calculation section calculates the movement position on the basis of a ratio of a second movement time to a first movement time. The temperature control section performs temperature control on the fixing member on the basis of the movement position calculated by the movement position calculation section, and the temperature measured by the temperature measurement sensor.
