Method for producing toner particles

A method for producing toner particles, comprising:

• a process (A) of obtaining resin particles
• in accordance with method i) or ii) below
• i) adding, to an aqueous medium, a polymerizable monomer composition that contains a polymerizable monomer, a colorant and a block polymer,
• obtaining a granulated particles by performing granulation of the polymerizable monomer composition, and
• polymerizing the polymerizable monomer contained in the granulated particles, to thereby produce resin particles;
• ii) preparing a resin solution by dissolving or dispersing a binder resin, a colorant and a block polymer in an organic solvent,
• adding the resin solution to an aqueous medium,
• performing granulation of the resin solution, and
• removing the organic solvent contained in the granulated particles, to thereby produce resin particles;
• and
• a process (B) of holding the temperature of the aqueous medium in which the resin particles obtained in the process (A) are dispersed, for 60 minutes or more, between a glass transition point TgA (° C.) of the resin particles and an onset temperature TmA (° C.) of an endothermic peak derived from the block polymer in the resin particles, in such a manner that
• a temperature fluctuation rate is not greater than 0.35° C./minute, and
• a temperature fluctuation range is not greater than 20° C.,
• wherein each of the toner particles contains:
• a) a binder resin having a styrene-acrylic resin as a main component;
• b) a colorant;
• and
• c) a block polymer;
• and
• the block polymer contains polyester segments and vinyl polymer segments, and has an endothermic peak in a measurement using a differential scanning calorimeter.
