Abstract

An image forming apparatus includes an apparatus body and an exhaust unit. The exhaust unit includes a first duct and a separating member. The first duct includes a first duct A forming member and a first duct B forming member provided with a plurality of communication ports which form one side surface of a second sheet transport path through which a sheet after heating and fixing is transported, a first exhaust fan for discharging air of the first duct to an outside of the apparatus body, and a filter disposed on a downstream side from the second sheet transport path. The first duct separates the second sheet transport path from spaces other than the first duct in the apparatus body. Further, the separating member separates the second sheet transport path from spaces other than the first duct in the image forming apparatus.
