A method for manufacturing a capsule toner, capable of obtaining a capsule toner including a coating layer having uniform thickness at high yield is provided. The method for manufacturing a capsule toner includes a fine resin particle adhering step of adhering fine resin particles to surfaces of toner base particles, a spraying step of spraying a spray liquid for plasticizing the toner base particles and the fine resin particles, while fluidizing the toner base particles and the fine resin particles, and a film-forming step of fluidizing the toner base particles and the fine resin particles until the fine resin particles adhered to the surfaces of the toner base particles are softened to form a film. In the spraying step, ultrasonic vibration is applied to set a number average liquid-droplet diameter of the spray liquid to less than 10 μm.
