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.
