| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a manufacturing method of electrostatic charge image developing toner which effectively utilizes polymer primary particle dispersion liquid of specified viscosity of off-specification which can not be used singly heretofore. SOLUTION: In the method of manufacturing toner by aggregating the dispersion liquid containing at least two kinds of polymer primary particles, the dispersion liquid is obtained by mixing at least two kinds of dispersion liquid which contain the polymer primary particles, and a viscosity (measurement temperature 150°C) of the polymer primary particles included in at least one kind of dispersion liquid departs from the range of 200 to 400 Pa s.
