Abstract
A method of producing a toner containing a toner particle, including the steps of: a) preparing a resin solution by mixing a resin A and an organic solvent, b) mixing the resin solution, a resin fine particle containing a resin B, and a dispersion medium to form a droplet of the resin solution whose surface has been covered with the resin fine particle, and c) removing the organic solvent in the droplet, in which the resin B is a polymer of a monomer composition containing a monomer X having polymerizable unsaturated groups at the both ends; the monomer X has a peak molecular weight of 5,000 to 50,000; the content of the monomer X is 0.10% to 3.00% by mol; and the following formula (1) is satisfied,
where SPA and SPX represent solubility parameters of the resin A and the monomer X, respectively.
