Summary:To provide an image forming apparatus that, when air warmed by a fixing unit passes through the inside of a duct, can prevent an electronic component mounted on a substrate inside an apparatus body from being heated by the air.SOLUTION: An image forming apparatus H comprises: a controller substrate 120 that is provided inside an upper cover 111 and a lower cover 112 that are exterior covers, and has an electronic component mounted thereon; a fan 97 for cooling the electronic component mounted on the controller substrate 120; a duct unit 200 that is attached to the upper cover 111 and lower cover 112, forms a channel for exhausting air warmed by a fixing unit to the outside of the apparatus body 1, and exhausts the air from a duct exhaust port 244; and a filter 260 that is provided inside the duct unit 200 and removes fine particles included in the air. The duct unit 200 is arranged at a position not overlapping the controller substrate 120 when viewed from the back side of the apparatus body 1.SELECTED DRAWING: Figure 18 【課題】定着部によって暖められた空気がダクトの内部を通過する際に、この空気によって装置本体内の基板に実装された電子部品が昇温することを抑制することができる画像形成装置を提供する。【解決手段】画像形成装置Ｈにおいて、外装カバーである上カバー１１１、下カバー１１２の内側に設けられ、電子部品を実装するコントローラ基板１２０と、コントローラ基板１２０に実装された電子部品を冷却するためのファン９７と、上カバー１１１、下カバー１１２に取り付けられ、定着部により暖められた空気を装置本体１の外部に排気するための流路を形成し、ダクト排気口２４４から排気を行うダクトユニット２００と、ダクトユニット２００の内部に設けられ、空気に含まれる微粒子を取り除くフィルタ２６０と、を備え、ダクトユニット２００は、装置本体１の背面側からみたとき、コントローラ基板１２０と重ならない位置に配置されている。【選択図】図１８
