<P>PROBLEM TO BE SOLVED: To air-cool a toner storage part storing toner and a transfer belt to which a toner image is transferred. <P>SOLUTION: Air flowing into a housing 60 from air ports 62A and 62B flows along a guide member 68, between the top plate part 62A of a top cover 62 and toner cartridges 44M, 44C and 44K and descends along an inclined part 62B, while being guided by a guide member 69, to flow toward a belt cover 70. The air sent to the belt cover 70 passes through through-holes 72 and 73, to be blown to an intermediate transfer belt 25. Then, the air blown to the intermediate transfer belt 25 is sent to the side of image forming units 13Y, 13M, 13C and 13K via the circumference of the intermediate transfer belt 25. <P>COPYRIGHT: (C)2010,JPO&INPIT |
