Abstract
There are provided a capsule toner, a two-component developer, and a capsule toner manufacturing method. The capsule toner in which a resin coating layer made of fine release-agent particles and fine resin particles is made on the surfaces of toner base particles, and thus excellent offset resistance without impairing blocking resistance can be obtained. The capsule toner includes toner base particles containing a binder resin and a colorant, and a resin coating layer made of fine release-agent particles and fine resin particles, for covering the surfaces of the toner base particles. The fine release-agent particles are dispersed in the resin coating layer.
