摘要： Flash fixing equipment for fixing a toner image onto a medium by means of flashlight is to reduce non-uniformity of halftone image print density. Flash fixing unit has flash energy distribution consisting of a center zone and front/end zones. The flash frequency of the flash lamp is controlled so that the toner fixing start energy being subtracted from the added value of flash energies of front and end zones becomes substantially equal to the flash energy value on the center zone. The energy distribution exceeding the fixing start energy which affects print density (size of toner-overflowed area) is controlled to have a flat characteristic to reduce non-uniformity of print density.
