Abstract:
1. A flash fixing device comprising: first and second flash lamps that emit light flashes that fix a toner image transferred onto a recording medium; and a light emission control unit that controls the light emission of the first and second flash lamps so that the light flashes emitted from the first flash lamp and the light flashes emitted from the second flash lamp are each irradiated at different timing on respective portions of the recording medium onto which the toner image is transferred, wherein the light emission control unit controls the light emission of the first and second flash lamps so that the first and second flash lamps each emit light at constant cycles, and so that a difference in irradiation timing of the light flashes from the first and second flash lamps to the same portion on the recording medium is less than half the light emission cycle of the first and second flash lamps.
