By using a duct, an image forming device in which an upper portion of a thermal fixing mechanism and an optical mechanism can be cooled. A fixing unit is disposed on the left side of the duct. A first auxiliary plate, which supports a scanner unit having a drive motor, is disposed above an upper opening of the duct. A process cartridge is disposed with its end next to the right side of the duct, and a second auxiliary plate is disposed below the duct. A power source is placed under the second auxiliary plate. Accordingly, cooling air from an intake fan is directed to four directions: between an upper portion of the fixing unit and the first auxiliary plate, to the underside of the first auxiliary plate, to the end of the process cartridge, and to the power source.
