PROBLEM TO BE SOLVED: To control the temperature rise in an image formation unit by heated sheets by providing a re-feeding device with a fan positioned in the rear face of a paper feeding cassette and blowing air to the bottom face of a sheet material carrier passage positioned in the top of the paper feed cassette with the top of the paper feeding cassette as a wind passage. SOLUTION: When a fan 23 is installed in a re-feeding device 3 and the re-feeding device 3 is installed in an image formation unit 1, the fan 23 is positioned in the rear face of the paper feeding cassette 2, blows an air in an arrow E direction, and cools the bottom face 3e of the re-feeding device 3 in its wide range. The sheet materials S are carried to S1 and most of the sheet materials S are in such states as touching or approaching to the top face of the bottom face 3a. Then, the wide range of the bottom face 3a is cooled by the fan 23 so that the sheet materials S heated by a fixing device 9 can be sufficiently cooled. |
