PROBLEM TO BE SOLVED: To provide an image forming apparatus which reduces cost by eliminating a filter while reducing ozone to be discharged, and achieves energy saving and noise reduction.SOLUTION: An image forming apparatus includes: a temperature sensor 215 which detects temperature in a casing; and a control unit 200 that controls operation driving speed which are rotation driving speed of fans during printing operation, and reduces the operation driving speed of the fans as compared with a case of exceeding a predetermined first threshold when the temperature is equal to or lower than the first threshold. |
