Method of producing toner
Provided is a method of producing a toner including the steps of: mixing a resin solution comprising a resin R, a colorant, and an organic solvent, a resin fine particle comprising a resin S containing an element α, and carbon dioxide to form a droplet having a surface covered with the resin fine particle; introducing carbon dioxide in a liquid state and pressurizing to extract the organic solvent in the droplet; and removing the extracted organic solvent together with the carbon dioxide to provide a toner particle. In the method of producing a toner, when the resin fine particle is treated with the carbon dioxide in a liquid state, a change in amount of the element α on the surface of the resin fine particle after the treatment as compared to the amount before the treatment falls within a specific range.
