Abstract:
1. A color image forming developer comprising yellow, magenta, and cyan toners, said yellow, magenta, and cyan toners containing an infrared absorber, wherein the cyan toner has a maximum infrared absorbance lower than a maximum infrared absorbance of the magenta toner and a maximum infrared absorbance of the yellow toner, said maximum infrared absorbance is determined in a wavelength range of from 800 to 1100 nm, wherein the infrared absorber incorporated into the cyan, magenta, and yellow toners at the following content ratios as represented by the following formulae (1) and (2): wherein, Kc: Content of an infrared absorber in the cyan toner, in parts by weight per 100 parts by weight of the cyan toner, Km: Content of an infrared absorber in the magenta toner, in parts by weight per 100 parts by weight of the magenta toner, and Ky: Content of an infrared absorber in the yellow toner, in parts by weight per 100 parts by weight of the yellow toner.
