Abstract
A fixing device includes a fixing rotary body rotatable in a predetermined direction of rotation and a heater disposed opposite and heating a heating span of the fixing rotary body. A controller is operatively connected to a power supply that supplies power to the heater and a driver that rotates the fixing rotary body to control the power supply and the driver. The controller performs at least one of a rotation speed control that controls the driver to rotate the fixing rotary body at an increased rotation speed and a power supply control that controls the power supply to supply an increased amount of power to the heater.
