PROBLEM TO BE SOLVED: To provide a low-cost compact image forming device made silent while saving energy without lowering cooling efficiency even when cooling air streams inside plural branch routes, which are branched and communicated to plural heating objects, are joined to be discharged. SOLUTION: This device is composed of an image forming means 1 for forming an image by transferring a forming image on an object (P) to be transferred, plural heating objects 2 to be heated when the image forming means 1 forms the image, a cooling air stream discharge branching and joining route 3 for joining and discharging plural cooling air streams branched and communicated to the heating objects 2 and a cooling air stream branching and joining route opening/closing means 4 for opening/closing the openings of one or plural branch routes 3 of the cooling air stream discharge branching and joining routes 3. |
