摘要：
A fixing device includes a fixing belt, a pressuring member, a heat source, a pressing member, a temperature sensor and a controller. A detected region whose temperature is detected by the temperature sensor is formed in the fixing belt, and an elastic layer of the detected region is provided with a hole in a part thereof in a circumferential direction. The controller judges that the fixing belt is rotating in a case where the temperature detected by the temperature sensor alternately increases and decreases in a state that the heat source is heating the fixing belt, and judges that the fixing belt is not rotating in a case where the temperature detected by the temperature sensor does not alternately increase and decrease in the state that the heat source is heating the fixing belt.
