Abstract
An image forming apparatus includes a fixing unit, wherein the fixing unit includes a first temperature detection member detecting the temperature of a first non-passing area of the fixing unit; a second temperature detection member detecting the temperature of a second non-passing area; and a cooling unit supplying air so as to simultaneously cool the first non-passing area and the second non-passing area, wherein the image forming apparatus is configured, when the absolute value of the difference between the detection temperature of the temperature detection members becomes not less than a threshold value, while air is being supplied to the non-passing area and the second non-passing area, to stop the supplying of air by the cooling unit and continue recording material fixing processing.
