PURPOSE:To provide an image forming device capable of completely pliminating the curling of a sheet regardless of the difference of the kind of the sheet, a moisture absorbing condition, and a peripheral environmental condition, etc. CONSTITUTION:In this image forming device provided with a heat roll fixing device 12, a belt carrying part 11 having a sucking duct 16 is provided on the entrance side of the heat roll fixing device 12, and an ejected paper belt carrying part 13 having a sucking duct 17 is provided on the exit side of the device 12. Since the sheet S on which a toner image is fixed is flatly streched and cooled by being sucked by the ejected paper belt carrying part 13 after coming out of the device 12, the curling on the sheet S formed by the device 12 is completely eliminated Heat circulation by means of air flow is formed between the sucking ducts 16 and 17, therefore, temperature difference between the heat roller 12a and the pressure roller 12b of the device 12 becomes small and the curling on the sheet S is restrained to be small. |
