Kind Code:
A
Abstract:

To provide a capsule toner, a two-component developer, and a method for producing the capsule toner, in which a resin coating layer composed of fine release-agent particles and resin fine particles is formed on the surfaces of toner base particles, and thus excellent offset resistance is provided without impairing blocking resistance.
