摘要:
The present invention provides a method for producing a toner including preparing an emulsified dispersion which contains emulsion particles by emulsifying or dispersing an oil phase containing at least a pigment and any one of a binder resin and a binder resin precursor in an aqueous medium, and granulating toner base particles by converging the emulsified dispersion, wherein the Casson yield value of the single oil phase before being emulsified or dispersed in the aqueous medium is 0.5 Pa to 20 Pa; and the temperature Tn of the emulsified dispersion in the preparation of the emulsified dispersion, the temperature Ts of the emulsified dispersion in the granulation of the toner base particles, and the glass transition temperature Tg of the toner base particles satisfy the relation Tn
