PURPOSE:To promote the thermal decomposition of ozone generated when an image is formed, to improve removal efficiency by a filter at the same time and to prolong the life of the filter or to miniaturize the filter and make it light in weight without damaging safety for a human body. CONSTITUTION:A conductor 36 leading to a housing 11 from the neighborhood of a photosensitive body 12 through the upper part of a heating and fixing roller 31 is provided in a device main body 10. Besides, a suction fan 37 which generates an air current toward the outside of the housing 11 is provided in the conductor 36. Simultaneously, the filter 38 is provided in the discharging port of the conductor 36. Then, the load of the filter is reduced and the air current is rectified at the same time by reducing the ozone in the air by the thermal decomposition in the conductor 36. As the result, the removal efficiency of the ozone by the filter 38 is improved. |
