Abstract
A capsule toner achieving both low temperature fixability and hot offset resistance, and a method of manufacturing the capsule toner are provided. A capsule toner includes a toner base particle containing a binder resin and a colorant, and a resin coating layer formed on a surface of the toner base particle. The resin coating layer includes a film of plural fine resin particles having different complex viscosities. The plural fine resin particles include first fine resin particles having complex viscosity at a softening temperature of the toner base particles of 5.0×10Pa·s or more and 1.0×10Pa·s or less, and second fine resin particles having complex viscosity at a softening temperature of the toner base particles of 1.0×10Pa·s or more and 1.0×10Pa·s or less.
