Abstract
A toner image fixing device is disposed above a passageway along which a sheet of paper carrying toner images recorded thereon is moved, and has a lamp for emitting heat-radiation toward the sheet of paper to thermally fuse and fix the toner images thereon. Emission of the heat-radiation from the lamp is controlled such that the energy of the heat-radiation, to which a high-density toner image zone of the sheet of paper is subjected, is smaller than that of the heat-radiation to which a low-density toner image zone of the sheet of paper is subjected, to thereby prevent undulation of the sheet of paper. Where two-sided recording is applied to the sheet of paper, the prevention of undulation of the sheet of paper is especially significant because then the two-sided recording can be properly carried out.
