• an apparatus main body that includes an image formation unit forming an image on a recording material;
• a fixation unit that includes a fixing unit fixing the image formed by the image formation unit onto the recording material and that is attachable to and detachable from the apparatus main body;
• a first duct that is attached to the fixation unit to face the fixing unit and through which a gas that cools the fixing unit flows;
• and
• a second duct that is attached to the apparatus main body to be adjacent to the first duct and through which a gas that cools the fixing unit flows,
• wherein the gas is sucked into the first duct at a position closer to an outside of the apparatus main body in comparison with the second duct.
