PROBLEM TO BE SOLVED: To provide an image formation apparatus that hardly have dust stuck on a light emission window of an exposure device although an air flow is generated in the image formation apparatus, and can be made compact.SOLUTION: When a waste toner box 37 is mounted on a front side of an image formation apparatus 1, opening ends of respective spaces SP are closed with respective removable members 37a of the waste toner box 37 to prevent respective light emission window glasses 11a from getting dirty with entering dust etc., and air flows in order through a suction fan 41, a third air flow passage A3 of a front duct D1, first air flow passages A1 of the respective removable members 37a, front-side connection air flow passages Af of respective front-side connection ducts 12e, and second air flow passages A2 in respective photoreceptor units 12 so as to cool inner parts of the respective photoreceptor units 12. Further, there is no unnecessary space among an optical scanner 11, the respective photoreceptor units 12, and respective development units 13, so that the image formation apparatus 1 can be made compact. |
