A temperature of a sheet material after passing a first fixing device and before entering a second fixing device changes between the start and the end of an image forming job, thus resulting in a change in the gloss of the toner image. A cooling apparatus for directly or indirectly cooling the sheet material is provided in a conveying path 25 between the first fixing device 10 and the second fixing device 20 thereby suppressing a change in the image gloss between the start and the end of the image forming job.
