Abstract
An image forming apparatus includes: an exhaust fan which has a pipe portion; and a duct. One of the pipe portion and the exhaust duct is inserted and fitted into the other such that they are connected to each other. A band-shaped seal member is attached to the entire outer circumference of the pipe portion. Both end portions of the seal member overlap each other in the circumferential direction of the pipe portion and are located a predetermined gap apart in an axial direction. The end portion of the seal member on the side of connection of the pipe portion has a non-fixed portion which is extended a predetermined length from a tip end in the circumferential direction and which is not fixed to the pipe portion, to reliably prevent an air leakage from a connection portion in a fan and a duct.
