To effectively recover vapor gas in flash fixing in a flash fixing device for fixing a toner image on a medium with flash light.
Since the vapor gas generated by the flash fixing flows in a medium carrying direction in the flash fixing device (13), the device (13) is provided with the gas absorption surface (15) of a gas recovery part (14) so as to receive the vapor gas flowing in the carrying direction. Alternatively, the device (13) is provided with a gas spraying part (16) at the post-stage of the recovery part (14). The vapor gas naturally flows to the surface (15), so that gas recovery efficiency is improved. Therefore, the vapor gas is recovered without increasing the suction force and the suction area of the gas recovery part even if printing speed for a medium becomes higher and the quantity of the vapor gas is increased. Then, the medium is prevented from fluttering in carrying, and the device is made smaller in size and more inexpensive.
