Abstract
A fixing device includes a fixing belt, a pressurizing member, a heat source, and a temperature sensing device. The fixing belt is rotatably provided. The pressurizing member is rotatably provided and is in pressed contact with the fixing belt to form a fixing nip between the pressurizing member and the fixing belt. The heat source heats the fixing belt. The temperature sensing device detects the temperature of the fixing belt. The temperature sensing device has a sensing element that is in contact with an inner circumferential surface of the fixing belt in a neighboring region of an end portion of the fixing nip and a pressing member configured to press the sensing element against the inner circumferential surface of the fixing belt.
