PROBLEM TO BE SOLVED: To provide an image forming device the air in whose main body can be efficiently discharged without disturbing the air current or the inside of whose main body can be efficiently cooled. SOLUTION: This image forming device has at least any of a fan for discharging the air in the device main body to the outside and a fan for introducing the outside air into the device main body. Plural opening parts 42 are formed on a cleaner cooling duct 38 connected to the fan and the cross sectional area of the duct 38 is made narrower as it goes from an air introducing port toward the inner part side. As a result, the air velocity can be made almost uniform in the whole area of the duct 38 and the air in the device main body can be efficiently discharged without disturbing the air current or the inside of the device main body can be efficiently cooled. |
