Disclosed is a method for producing an electrostatic charge image developing toner excellent in low-temperature fixability against cold, cold offset, hot offset resistance, and filming resistance, and the toner. An emulsifier in which a peripheral speed of a stirring blade is controlled to 15 to 25 m / s, an organic solvent, a binder resin, a colorant, and a release agent in which a dispersed particle size is adjusted to 0.15 to 0.7 μm in advance. An oil phase containing water and an aqueous phase are fed, and continuously dispersed and / or emulsified to satisfy the following formulas (1) to (3) to form an oil phase, and a dispersion / emulsion liquid containing the particles is obtained. After being transported to the storage tank, the solvent is removed from the dispersion / emulsion, and toner particles are obtained through a drying process. 3.0 ≦ Dv ′ ≦ 6.0 Formula (1), 4.0 ≦ Dv ≦ 7.5 Formula (2), 1.0 ≦ Dv−Dv ′ ≦ 3.0 Formula (3), where Dv ′ and Dv are the outlet of the emulsifier and The volume average particle diameter of the particles in the dispersion / emulsion in the storage tank is shown. ] [Selection] Figure 1 |
