Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an image formation apparatus which can prevent leakage of steam generated in a fixation device from a discharge port.SOLUTION: An image formation apparatus includes: a fixation device which heats a toner image to fix the toner image on a sheet; a discharge port which is formed on one surface of the apparatus body and to which the sheet fixed with the toner in the fixation device is discharged; a sheet conveyance path which heads from the fixation device to the discharge port; an exhaust port which opens to the outside of the apparatus body; and an exhauster 40 which exhausts the steam generated in the fixation device from the exhaust port to the outside. The exhauster 40 includes: a duct 42 which is provided along the sheet width direction orthogonal to the sheet conveyance direction and communicates the space on the side of the conveyance path with the outside via the exhaust port; and a fan 43 which exhausts the air in the conveyance path via the duct 42. The duct 42 includes: a guide part 42a which is provided so as to face the conveyance path and guides the sheet; and a suction port 53 which is provided in the guide part 42a.SELECTED DRAWING: Figure 4
【課題】定着装置で発生した水蒸気の排出口からの漏れを防止できる画像形成装置を提供する。【解決手段】画像形成装置は、トナー像を加熱して用紙に定着する定着装置と、装置本体の一面に形成されて、前記定着装置においてトナーが定着された用紙が排出される排出口と、前記定着装置から前記排出口へ向かう用紙の搬送経路と、前記装置本体の外部に開口する排気口と、前記定着装置で発生する水蒸気を前記排気口から外部へ排気する排気装置40と、を備える。前記排気装置40は、用紙の搬送方向と直交する用紙幅方向に沿って設けられて、前記搬送経路の側の空間と外部とを前記排気口を介して連通するダクト42と、前記搬送経路内の空気を前記ダクト42を介して排気するファン43と、を有する。前記ダクト42は、前記搬送経路に面して設けられて、用紙を案内するガイド部42aと、該ガイド部42aに設けられる吸気口53と、を有している。【選択図】図4 |
