Abstract:
A color image forming apparatus which forms a color image on a recording medium by using a toner comprising at least a binding resin, a coloring agent and an infrared ray absorbent, and a light source for causing the toner to melt,wherein: said light source has a plurality of light emission peaks having wavelengths of &lgr;, &lgr;2, &lgr;3, &lgr;n within a full range inclusively beginning from 300 nm and ending at 1100 nm; and setting is made such that at least the following relationship is satisfied: |&lgr;1âˆ’&Lgr;1|<100 nm, and, also, |&lgr;2âˆ’&Lgr;2|<100 nm â€ƒwhere &lgr;1 and &lgr;2 denote the wavelengths of said light emission peaks; and where &Lgr;1 and &Lgr;2 denote wavelengths of absorption peak wavelengths of said infrared ray absorbent: wherein the energy of said light source is within a full range inclusively beginning from 2.0 and ending at 6.0 J/cm2 when superimposing of four colors.
