Abstract
A fixing device includes a heating member, a first heater configured to heat a first area, a second heater configured to heat a second area, a first temperature detector, a second temperature detector, and a controller. The controller executes a heating control in which the first heater is energized based on the temperature of the first area so that the temperature of the first area is within a first temperature range and the second heater is energized based on the temperature of the second area so that the temperature of the second area is within a second temperature range. In the heating control, the controller executes (i) a first energizing processing, and (ii) a second energizing processing of energizing the second heater at the timing when the first energizing processing is stopped.
