A method for producing a toner comprising:
- aggregating first particles and second particles to form aggregated particles, the first particles having a volume average particle diameter of 0.01 to 2.0 μm, the second particles having a volume average particle diameter of 2.0 μm or more, the volume average particle diameter of the second particles being greater than the volume average particle diameter of the first particles, each of the second particles having a core and a shell encapsulating the core, and the core containing a medium and a component that is dispersed in the medium and imparts a predetermined function to the toner.
