Summary:To devise the configuration of a duct in an image forming apparatus to reduce ventilation resistance, thereby improving exhaust efficiency.SOLUTION: An image forming apparatus 1 comprises: a drum unit; a power supply section 70; an exhaust fan 81 that exhausts air inside the apparatus to the outside; and a housing 2 that includes a duct 23 having a first partition wall 231 that partitions a first channel 23A guiding air from the drum unit toward the exhaust fan 81 and a second channel 23B guiding air from the power supply section 70 toward the exhaust fan 81 from each other. The first partition wall 231 is in contact with or proximity to the exhaust fan 81 at one end.SELECTED DRAWING: Figure 3 【課題】画像形成装置においてダクトの構成を工夫することにより、通風抵抗を低減して排気効率を向上させる。【解決手段】画像形成装置１は、ドラムユニットと、電源部７０と、装置内のエアーを外部に排出する排気ファン８１と、ドラムユニットからのエアーを排気ファン８１に向かって導く第１流路２３Ａと、電源部７０からのエアーを排気ファン８１に向かって導く第２流路２３Ｂと、を仕切る第１仕切り壁２３１を有するダクト２３を備える筐体２と、を備える。第１仕切り壁２３１は、一端が排気ファン８１に当接又は近接する。【選択図】図３
