Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a capsule toner by which production of coarse powder can be suppressed and a resin coating layer having uniform layer thickness can be formed, and to provide a capsule toner and a developer.SOLUTION: The method of manufacturing the capsule toner includes a resin fine particle preparing step, an adhering step, a spraying step and a film-forming step. In the resin fine particle preparing step, dried resin fine particles are obtained by injecting the dispersion liquid of resin fine particles into the atmosphere of shock waves by pulse combustion so as to volatilize the dispersion medium in the resin fine particle dispersion liquid. In the adhering step, toner base particles with adhered resin fine particles are obtained by stirring and mixing toner base particles and the resin fine particles to adhere the resin fine particles to the surfaces of the toner base particles. In the spraying step, a spray liquid is sprayed to the toner base particles with adhered resin fine particles while stirring. In the film-forming step, a resin coating layer is formed on the surface of the toner base particle by continuing stirring until the resin fine particles on the surfaces of the toner base particles with adhered resin fine particles are softened to form a film.
