Summary:PROBLEM TO BE SOLVED: To provide a ventilation system that can suppress a resonance sound that is generated when a duct is periodically bent to vibrate and resonate when an air sent from a ventilation device passes through the duct and to provide an image forming apparatus including the same.SOLUTION: There is provided a ventilation system including a ventilation device and a duct that guides an air sent from the ventilation device. The duct has a surface area reduction part for reducing the surface area of continuous surfaces provided in at least a part of the outer surface. 【課題】送風装置により送られる空気がダクト内を通過するときにダクトが周期的に撓むことにより振動して共鳴する際の共鳴音の発生を抑制することができる送風システム及びそれを備えた画像形成装置を提供する。【解決手段】送風装置と送風装置により送られる空気を案内するダクトとを備えた送風システムである。ダクトの外表面の少なくとも一部には、連続する面の表面積を小さくするための表面積低減部が設けられている。【選択図】図１４
