PROBLEM TO BE SOLVED: To exhaust 1st air warmed by a fixing device without causing trouble even when a fan is not made large or the number of fans is not increased by forming 1st and 2nd air courses and making the 1st air and the 2nd air flow separately. SOLUTION: The 2nd air including ozone produced in a transfer electrifier 28 passes in the 2nd air course shown by a void arrow H and is discharged to the outside of the device. Namely, by rotating an axial fan 70, the 2nd air passes under a cleaning device 30, passes through an ozone filter 72 and the fan 70 in order, and then is exhausted to the outside via a duct 86. The 1st air warmed by the fixing device 44 passes in the 1st air course shown by an arrow J and is discharged to the outside of the device. Namely, the air warmed by the device 44 rises as ascending current, is guided to a space 88 and discharged to the outside of the device together with the air flowing in the air courses shown by the arrows G and H. Therefore, the air warmed by the device 44 is discharged to the outside of the device without passing through the filter 72 and the fan 70. |
