Abstract A flash fixing apparatus is provided for fixing an unfixed toner image on a base material by light radiated from a flash lamp. The apparatus includes a conveyor mechanism (1) for conveying the base material, the flash lamp (4) for radiating light toward the unfixed toner image on the base material which is being conveyed by the conveyor mechanism (1), and an auxiliary heating system for additionally heating the base material. The conveyor mechanism (1) comprises a negative pressure compartment having an upper board (21), through which a plurality of suction holes (22) are formed, and a plurality of conveyor belts (11) arranged spacedly from one another in such a manner that the coveyor belts are caused to move over the upper board (21) of the negative pressure compartment (2). The auxiliary heating system comprises at least one auxiliary heater (3) disposed within the negative pressure compartment (2) and adapted to heat the upper board (21) of the negative pressure compartment (2).
