Method of producing toner and method of producing resin particle

A method of producing a toner comprising a toner particle, the method comprising 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, wherein:
• the resin B is a polymer of a monomer composition comprising a monomer X having polymerizable unsaturated groups at the both ends;
• the monomer X has a peak molecular weight of 5,000 or more and 50,000 or less;
• the content of the monomer X is 0.10% by mol or more and 3.00% by mol or less based on a total amount of monomers of the monomer composition, and
• the resin A and the monomer X satisfy the following formula (1),
• |SPX−SPA|≦2.0 (1)
• where
• SPA represents a solubility parameter of the resin A, and
• SPX represents a solubility parameter of the monomer X.
