PURPOSE:To evade a partial deterioration, to prolong the life of a filter, and to improve an ozone decompos ability by providing an air flow regulating means on the upper stream side of the filter of an air exhausting path and uniformizing the distribution of one of a discharged air quantity and a peripheral speed or both of them, on the filter. CONSTITUTION:In this image forming device having a discharge fan 17 forcibly exhausting air inside a device outside the device and the filter 21 provided on the air exhausting path 20 by the discharge fan 17, the air flow regulating means 31 is provided on the upper stream side than the filter 21 of the air exhausting path 20. An air flow by the discharge fan 17 is regulated by the means 31, so that one of a wind-speed and an air quantity or both of them, on the entire surface of the filter 21, are uniformized. Therefore, the ozone removing ability or decompos ability of the filter 21 is totally uniformized, and totally deteriorated at the time of a deterioration. Thus, the life can be prolonged, and moreover, the ozone removability or the ozone decompos ability can be totally and efficiently displayed. |
