PROBLEM TO BE SOLVED: To prevent dew condensation of a sheet storing part (intermediate conveying unit), while suppressing resistance between sheets. SOLUTION: This intermediate conveying unit 200 is provided with: a heater 10 mounted on an outer peripheral surface of a guide plate 72 of an accumulating part 62; a temperature sensor part for measuring the temperature of the guide plate 72; and a control part for controlling operations of the heater 10 and the temperature sensor part. When the control part determines that the temperature of the guide plate 72 acquired from the temperature sensor part is less than a dew condensation temperature, based on a relation between temperatures and humidity of the accumulating part 62 and the sheet S, the control part controls to heat the guide plate 72 by switching the heater 10 to ON. As a result, a temperature difference between the temperature of the guide plate 72 and an internal temperature of the accumulating part 62 is set to a range generating no dew condensation, and thereby dew condensation generated due to a temperature difference in the intermediate conveying unit 200 is prevented.
