PURPOSE:To prevent rising of temperature in the device by providing an air supplying fan in the copying device main body and lowering the ozone concentration in the device. CONSTITUTION:An ozone decomposing means 2 containing ozone decomposing agent is provided in an exhausting part of the copying device main body 1, the air containing ozone in the device is passed by an exhausting fan 3 through this ozone decomposing means 2, while passing through, the ozone is decomposed by contact of the ozone decomposing agent and the exhaust air, and is exhausted outside the device. Further, the air feeding fan 4 is provided near the exhausting fan 3 of the copying device main body 1, and the driving means 9 of the exhausting fan 4 is controlled by the controlling means 8. Thus, the ozone concentration in air in the device is lowered and the temperature in the device can also be lowered. |
