PROBLEM TO BE SOLVED: To provide a production method of a toner for electrostatic charge image development, by which a toner excellent in low-temperature fixability and capable of suppressing reduction in the low-temperature fixability with time can be obtained.SOLUTION: The production method of a toner for electrostatic charge image development includes the following steps (1) to (3): a step (1) of mixing wax and an aqueous dispersion of resin particles (A) to obtain an aqueous dispersion of wax particles; a step (2) of mixing and coagulating the aqueous dispersion of wax particles obtained in the step (1) with an aqueous dispersion of resin particles (B) and an aqueous dispersion of resin particles (C) to obtain coagulated particles; and a step (3) of fusing the coagulated particles obtained in the step (2) to obtain fused particles. The resin constituting the resin particles (A) comprises a polyester-based resin containing a polyester segment (a1); the resin constituting the resin particles (B) comprises a crystalline polyester (b); and the resin constituting the resin particles (C) comprises a composite resin (c) containing a polyester segment (c1) and a vinyl-based resin segment (c2) having a structural unit derived from a styrene compound.SELECTED DRAWING: None |
