摘要： 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.
