<P>PROBLEM TO BE SOLVED: To appropriately perform the cooling of a recording medium on which an image has been already heat-fixed and the prevention of the temperature of a part other than a fixing part (especially, an image reading part arranged on the upside of a fixing device) from getting high, and also to prevent heat from being taken away from the fixing part to the utmost. <P>SOLUTION: By providing an exhaust duct 51 and a ventilating fan 52 for exhausting air at a position on the upside of a 2nd carrying path 43 in the case of guiding the recording medium (paper) on which the image has been already heat-fixed by the fixing part 21 of the image forming apparatus X to the upside in a 1st carrying path 42 and further guiding it in a nearly horizontal direction in the 2nd carrying path 43, the heat is taken away from the recording medium passing through the 2nd carrying path 43, and a situation that the heat is transmitted to the part other than the fixing part 21 (especially, the copying lamp unit 32 of the image reading part 1 arranged on the upside of the fixing device) from the heated air generated in the fixing part 21 and the temperature of such a part gets high is prevented. Furthermore, the 2nd carrying path 43 and the recording medium passing through the carrying path 43 function as a heat insulating layer so as to prevent a situation that the heat is taken away from the fixing part 21 (the fixing part 21 is cooled) more than necessary. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
