PURPOSE:To facilitate the maintenance-replacement work of an exhaust fan and an ozone suction filter by accommodating the exhaust fan and ozone suction filter in one case, and forming this case in such a way as to be removable from a device body. CONSTITUTION:An exhaust fan and an ozone suction filter are accommodated removably to form one exhaust unit 42, and the case 41 of the exhaust unit 42 is removably provided in the specified position 22 of a device body 10. That is, the case 41 and the device body 10 are provided with a plug fit socket 44 and an attachment plug 45 to be inserted mutually. The device body 10 is also provided with an interlocking switch 47. Accordingly, when the case 41 is mounted into the removable position 22, an operating member provided at the case 41 pushes the interlocking switch 47 to turn it on so that power supply such as the high pressure power supply in the device body 10 and the power supply of a fixing device is turned on. When the case 41 is removed, the operation to the interlocking switch 47 is released, and various switches of the power supply are turned off. |
