PROBLEM TO BE SOLVED: To provide a method for producing a capsule toner having a uniform resin coating layer and a narrow particle size distribution, the capsule toner, and a developer. SOLUTION: The method for producing the capsule toner includes the steps of: depositing resin particulates on surfaces of toner base particles by making the toner base particles and the resin particulates flow to apply a mechanical impact force; spraying a liquid obtained by dispersing hydrophobic silica particulates in a polar organic solvent, onto the toner base particles which are in a fluid state and have the resin particulates deposited on the surfaces thereof; and forming the resin particulates having the hydrophobic silica particulates deposited thereon, into films by the impact force to form resin coating layers on the surfaces of the toner base particles.
