PURPOSE:To prevent the temperature of a device from rising because of discharged air by connecting the inflow port of an exhaust duct to a ring blower and opening an outside air taking-in slit in a part of the duct. CONSTITUTION:An exhaust duct 1 whose sectional area of a flow passage is increased toward an exhaust port 1a is attached under a machine frame 4, and a ring blower 3 is connected to the flowin port 1b of the duct 1 through a hose 2. The outside air taking-in slit is provided on the lower face of the duct 1. Since the external air at a low temperature is mixed with air at a high temperature which passes the ring blower 3 for exhaust and toner gathering to cool the air and it is discharged, the rise of the temperature of the device due to discharged air is prevented to stabilize the quality of output data.
