Method of producing toner

A method of producing a toner comprising a toner particle, the method comprising the steps of:

• (e) mixing a resin R, a colorant, and an organic solvent to prepare a resin solution;
• (f) mixing the resin solution, a resin fine particle, and carbon dioxide in a pressure container to form such a dispersion that a droplet of the resin solution having a surface covered with the resin fine particle is dispersed in a dispersion medium comprising the carbon dioxide;
• (g) introducing carbon dioxide in a liquid state into the pressure container and pressurizing the pressure container to extract the organic solvent in the droplet into the dispersion medium;
• and
• (h) removing the organic solvent extracted into the dispersion medium from an inside of the pressure container together with the carbon dioxide to provide a toner particle, wherein
• the resin fine particle comprises a resin S containing an element α, the resin S being a polymerized product of a monomer composition comprising an organic polysiloxane compound having a vinyl group, and a polyester having a polymerizable unsaturated group,
• the polyester being a polycondensate of a dicarboxylic and a diol, and the polymerizable unsaturated group of the polyester is derived from at least one of a dicarboxylic acid having the polymerizable unsaturated group and a diol having the polymerizable unsaturated group, an average number of polymerizable unsaturated groups in one molecule of the polyester being 1.5 to 2.5,
• the resin fine particle satisfies formulae (1) and (2):
• 3.0≦A≦6.0 (1)
• 1.10≦B/A≦1.55 (2)
• where “A” represents an amount (atomic %) of the element a of the resin fine particle measured by X-ray photoelectron spectroscopy (ESCA), and
• “B” represents an amount (atomic %) of the element a of a treated resin fine particle measured by the X-ray photoelectron spectroscopy, the treated resin fine particle being obtained by
• loading a dispersion obtained by dispersing the resin fine particle in the organic solvent into the pressure container,
• introducing carbon dioxide into the pressure container, and
• flowing carbon dioxide through the pressure container while maintaining a pressure in the pressure container at 6.5 MPa and a temperature in the pressure container at 25° C. to remove the organic solvent from the dispersion.
