PROBLEM TO BE SOLVED: To provide a method of manufacturing a toner with which toner particles having a sharp particle size distribution and uniform shapes can be easily and efficiently obtained.SOLUTION: There is provided a method of manufacturing a toner containing toner particles of a core-shell structure including a core that contains a resin and a shell phase that is provided on the surface of the core and derived from resin fine particles containing a resin A, in which the resin A is a resin containing a portion derived from a crystalline polymer D. The method includes the steps of: (i) preparing a dispersion element by dispersing, in a dispersion medium in a container, liquid droplets of a resin solution containing a resin, resin fine particles, and organic solvent; and (ii) extracting the organic solvent included in the droplets of the resin solution in the dispersion medium and then removing the organic solvent from the dispersion medium, wherein in the step (i), the temperature of the dispersion element is maintained higher than a temperature Ta(°C), and between the step (i) and the step (ii), the method further includes a step (iii) of cooling the dispersion element to a temperature lower than the temperature Ta(°C).SELECTED DRAWING: None |
