PROBLEM TO BE SOLVED: To concentrically evacuate hot air in an image forming device by connecting a piping to an exhaust duct forming the flow of air, connecting the image forming device to the piping and evacuating the air from the piping in the image forming device through the exhaust duct. SOLUTION: Main bodies 1A to 1G are respectively connected to the exhaust duct 3 through the pipings 2, and a ventilating fan 4 is provided at one end of the duct 3 so as to suck and discharge the air in the duct 3. The other end of the fan 4 communicates outdoors, and the air in the duct 3 is discharged outdoors. By such constitution, the heat generated inside the device of the main body 1 is sucked to the duct 3 through an air duct and the piping 2. Since the flow of the air is formed inside the duct 3 by the action of the fan 4, the sucked heat is discharged outdoors through the fan 4 soon. Thus, the air inside the device is concentrated at one spot and evacuated through the duct 3. |
