PURPOSE:To suppress the concentration of exhaust ozone at a low cost by providing a heat conduction member between a heat transfer member and a heater of a fixing device, and leading heat generated by the heater of the fixing device to the heat transfer member. CONSTITUTION:Air containing ozone and an ozone product generated from a primary electrifier, etc., used for an image forming process by an electrophotographic system is sucked into an enclosure 20 from a hood 24 ad indicated with an arrow B. In this case, a heat pipe 21 uses the heater 19 of a fixing device as a heat source and allows radiation heat of a tube wall the conduct to a heat transfer member 23. Accordingly, air containing ozone and an ozone product is cracked instantaneously by high heat at the time of passing through the heat transfer member 23. In such a manner, the concentration of ozone in air exhausted in the direction as indicated with an arrow C from an exhaust fan 25 can be suppressed to a UL standard value or below. |
