Summary:To provide an image forming apparatus on which a plurality of sizes of process cartridges can be selectively mounted, the image forming apparatus capable of efficiently cooling the process cartridge.SOLUTION: In an image forming apparatus A, when a process cartridge 10 is mounted, air taken in from a suction part to the inside of the image forming apparatus A flows through a space H1 surrounded by a housing 10a, a contact part 52, and an arm part 51 of the process cartridge 10 and is exhausted from an exhaust part, and when a process cartridge 20 having a larger housing than that of the process cartridge 10 is mounted, air taken in from the suction part to the inside of the image forming apparatus A flows through a space H3 surrounded by a housing 20a, a contact part 53, and an arm part 51 of the process cartridge 20 and is exhausted from the exhaust part.SELECTED DRAWING: Figure 2 【課題】複数サイズのプロセスカートリッジを選択的に装着可能な画像形成装置において、プロセスカートリッジを効率的に冷却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Ａにおいて、プロセスカートリッジ１０が装着されているとき、吸気部から画像形成装置Ａの内部に取り込まれた空気がプロセスカートリッジ１０の筐体１０ａ、接触部５２、アーム部５１によって囲まれた空間Ｈ１を流れて排気部から排気され、プロセスカートリッジ１０よりも筐体が大きいプロセスカートリッジ２０が装着されているとき、吸気部から画像形成装置Ａの内部に取り込まれた空気がプロセスカートリッジ２０の筐体２０ａ、接触部５３、アーム部５１によって囲まれた空間Ｈ３を流れて排気部から排気される。【選択図】図２
