Image forming apparatus
An image forming apparatus has a fusing unit including a first rotor provided with a heat-generating unit and an elastic layer, as well as a second rotor provided in direct contact with the first rotor, the fusing unit fixing a toner image on a sheet, and a duct for allowing an inlet and an exhaust outlet to communicate with each other, the inlet being adapted to allow a current of air derived from the fusing unit to flow in, the exhaust outlet facing toward the outside of the apparatus. The duct includes an introduction channel for guiding and jetting out air taken in from the inlet, a main channel for guiding the air jetted out of the introduction channel to the exhaust outlet, and a cul-de-sac provided in communication with the main channel at one end and closed at the other end.
