<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus for uniformly and effectively cooling a plurality of image forming units by a cooling fan. <P>SOLUTION: The air outlet 52a of the cooling fan 52 and a toner box 51 can be connected by flexible tubes 53 to 56. The flexible tubes 53 to 56 have different inner diameters. Thus, even when rising temperature varies among the image forming units 26 to 29 due to heat generated from a high heat generating area, the amount of blown cooling air is varied so that the respective image forming units 26 to 29 can be uniformly and effectively cooled by the cooling fan. <P>COPYRIGHT: (C)2008,JPO&INPIT |
