PROBLEM TO BE SOLVED: To provide a toner manufacturing method for improving transfer efficiency in a high-speed full-color image forming method, eliminating an image defect at each transfer, and outputting a long-term reproducible image, and using the toner It is an object of the present invention to provide a full color image forming method and a process cartridge. In a method for producing a toner for obtaining toner by surface-treating colored particles, a step of adjusting the colored particle dispersion by dispersing the colored particles in an aqueous medium containing at least a surfactant, and the colored particles A surface treatment step of heating the dispersion, wherein the amount of the surfactant in the colored particle dispersion in the surface treatment step is 0.1 to 2.0 times the critical micelle concentration of the surfactant, A method for producing a toner, wherein a heating temperature (T1) in the surface treatment step is −10 ° C. or more and less than 10 ° C. with respect to a glass transition temperature (Tg) of the toner.
