A color image forming apparatus forms a color image on a recording medium by using a toner comprising a binding resin, a coloring agent and infrared ray absorbent, and a light source for causing the toner to melt. The light source has a plurality of light emission peaks having wavelengths of lambd1, lambd2, lambd3, . . . , lambdn in a range of 500 nm through 3000 nm. Setting is made such that the following relationship is satisfied: |lambd1-LAMBD1|<100 nm, and, also, |lambd2-LAMBD2|<100 nm, where LAMBD1 and LAMBD2 denote the wavelengths of absorption peak wavelengths of the infrared ray absorbent.
