Abstract
A fixing device includes: a plurality of laser irradiation sections each of which emits a laser beam whose wavelength exhibits an absorbance of 80% or more with respect to a corresponding toner; and a control device for controlling the plurality of irradiation sections so that in order to fuse a black toner, (i) a laser irradiation section corresponding to the black toner among the plurality of laser irradiation sections irradiates the black toner with a laser beam thereof, and (ii) the other laser irradiation sections irradiate the black toner with laser beams thereof, where the other laser irradiation sections do not correspond to the black toner among the plurality of laser irradiation sections. Therefore, it is possible to provide a laser fixing device which can fix a color toner while preventing an increase in size of the fixing device as much as possible.
