Abstract
An image forming apparatus includes a housing in which an exhaust port is formed, a fan, a duct extending in an exhausting direction and configured to accommodate the fan, the duct including a downstream end in the exhausting direction, and an exhaust filter disposed between the duct and the exhaust port in the exhausting direction, the exhaust filter including a first surface facing the exhaust port and a second surface facing the duct. Dimensions of the duct each orthogonal to the exhausting direction are smaller than dimensions of the exhaust filter each orthogonal to the exhausting directions. A perimeter of the downstream end of the duct in the exhausting direction is in contact with the second surface of the exhaust filter.
