PROBLEM TO BE SOLVED: To provide a structure for cooling a developing device which can restrain air from leaking, and which makes only an effective air flow so that the developing device can be effectively cooled. SOLUTION: This cooling structure is provided with a stirring means 3 for stirring developer with a tube shaft 9, a positioning part 7 fitted to the one end 20 of the shaft 9 for positioning the developing device 1 to an image forming device, a cooling means 8 provided on the fixing member 5 of the image forming device, and an air leaking preventing means preventing the leaking of air other than the air flow from the shaft 9. An aperture part 21 and an aperture 22 are opened toward the means 8, and the air inside the shaft 9 is made flow to cool the developing device by the means 8. |
