Further, the fixing device control unit stops the rotation of the heating rotary body and performs a second stand-by control process that makes the fixing device stand by, without heating the heating rotary body with the heating member, when the determining unit determines that the temperature of the heating rotary body is the stand-by temperature or higher.
