PROBLEM TO BE SOLVED: To provide a color toner for electrostatic latent image development which satisfies both of contradicting characteristics of transparency and electrostatic charge stability at a high level and further excels in color reproducibility, colorability, etc. SOLUTION: The color toner which is packed into a developing unit 19 of an image forming apparatus 100 and is used for development of the electrostatic latent image formed on the surface of a photoreceptor 16 is prepared by sticking a pyrolyzable polar group to a pigment surface to uniformly disperse the pigment into a binder resin, decomposing the pyrolyzable polar group by heating at the time of dispersion, and regulating the content thereof to≤1.0 KOHmg per 1 g of the toner. Since the toner is excellent in both of the transparency and the electrostatic charge stability, the toner is capable of forming an image of high sharpness and high grade having the excellent color reproducibility, colorability, etc., for a long period of time.
