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.degree. 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/cm.sup.2. A relaxation time .lamda. corresponding
to the minimum value is in a range of about 1 to 10,000 sec.
