    Abstract: The invention provides a color image forming method including charging, developing, transferring and fixing. The fixing includes thermally fixing a toner image to paper by using a heating body and a pressurizing member which is positioned opposite to the heating body via a film-like member. The color toner includes a toner particle containing a crystalline resin and a non-crystalline resin. When the color toner is subjected to dynamic viscoelasticity measurement employing a sine wave vibration method, a minimum value of the relaxation elasticity H in a relaxation spectrum obtained from frequency dispersion characteristics when a measurement frequency measured at 60 and 80° C. is 0.1 to 100 rad/sec and a measurement strain at a frequency of 6.28 rad/sec is 0.1 %, is in a range of about 10 to 900 Pa/cm2. A relaxation time λ corresponding to the minimum value is in a range of about 1 to 10,000 sec.
