PURPOSE:To prevent the deterioration of the characteristics of a photosensitive body by installing an enclosed container which houses on ozone decomposing agent having volatility and where a small opening for gradually volatilizing it is equipped and setting said container in a position where the votatile ozone decomposing agent flows toward an ozone filter. CONSTITUTION:The enclosed container 35 housing the ozone decomposing agent 36 having the volatility, where the small opening 37 for gradually volatilizing said ozone decomposing agent 36 is installed, is arranged between an exhaust fan 32 and the ozone filter 34 so that the volatile ozone decomposing agent 36 discharged from the opening 37 flows toward the ozone filter 34. Since the volatilized ozone decomposing agent 36 flows to the ozone filter 34 and the ozone adsorbed in the ozone filter 34 is decomposed, also the volatile ozone decomposing agent 36 flows to the ozone filter 34 side, it does not allow to react with the photosensitive body. Thus, the deterioration of the characteristic of the photosensitive body can be prevented. |
