PURPOSE:To discharge air from an exhaust fan through an pen part even if an ozone filter is clogged by providing the open part between the filter for absorbing the ozone generated from a photosensitive body and the exhaust fan which discharges the air flow passing the filter. CONSTITUTION:Slopes 23, 24 are formed upward from a projecting part 22 between the photosensitive body 10 and a heat fixing part 20. An aperture 25 mounted with the auxiliary ozone filter 29 is provided to the slope 23. A discharge port 26 is formed to a side plate 3 and the ozone filter 27 and the exhaust fan 28 for the air flow past the filter are provided therein. The open part 38 is formed between the filter 27 and a spacer 36 of the fan 28. The air in the photosensitive body 10 and the heat fixing part 20 flows through the filters 29, 27 as well as through the discharge hole 26 and the slope 24 to the discharge hole 26. The air is, therefore, passed through the filter 27 when the filter 29 is clogged. The air is sucked from the open part into the fan 28 when the filter 27 is clogged. |
