<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of making the quality of a formed image high and stable by completely guiding air taken in from an air flow generation part (cooling fan) to the inner side from the front side of a part to be cooled, whereby temperature rise is suppressed to the inner side of the part to be cooled. <P>SOLUTION: The image forming apparatus has the cooling fan 52 for taking in the air outside the apparatus, and flexible tubes 53 to 56 guiding the air taken in to four color toner boxes 51 and cooling the toner boxes 51. The flexible tubes 53 to 56 have introducing parts 53b to 56b taking in the air from the cooling fan 52, and blow-off parts 53a to 56a sending air to the respective toner boxes 51. The cross sectional area of the respective blow-off parts 53a to 56a where the air circulates is smaller than that of the introducing parts 53b to 56b. <P>COPYRIGHT: (C)2009,JPO&INPIT |
