Abstract
An exhaust air cleaning apparatus includes a cleaning duct for cleaning air to be exhausted from an exhaust port of an image forming apparatus. In the cleaning duct, a fan and a filter are provide between an inflow part connected with the exhaust port of the image forming apparatus and a discharge port for discharging air from the inside of the cleaning duct. The exhaust air cleaning apparatus further includes a pressure adjusting part for adjusting the pressure in the cleaning duct. The pressure adjusting part performs pressure adjustment so that the pressure at a pressure adjusting position located between the inflow part and the fan in the cleaning duct falls within an appropriate pressure range determined in advance to be equal to or less than atmospheric pressure.
