Abstract: An image forming apparatus includes a plurality of image forming units for forming an image on a printing medium such as a sheet of paper. A plurality of color types of toner are arranged on a transport path of the printing medium. Toner images corresponding to the color types of toner are color-by-color transferred onto the printing medium. Light emitted from a flash lamp melts and fixes the toner images. The fixing order of the toner images corresponding to the color types of toner is decided so that the toner images are fixed in ascending order of toner's absorptivity of the light emitted from the flash lamp or in descending order of toner's reflectivity of the light.

Abstract: A flash fixing apparatus effectively collect vapor gas produced at the time of fixation while fixing a toner image of medium by means off flashlight. In the flash fixation unit, vapor gas produced in flash fixation flows toward the medium transportation direction. Utilizing this phenomenon, a gas suction face is provided in a gas collector so as to receive the vapor gas flowing toward the medium transportation direction. Otherwise, a gas blast portion is provided at the rear stage of the gas collector. The vapor gas flows to the gas suction face naturally, bringing about improved gas collection efficiency.
