Abstract
A toner includes a core containing a binder resin, wax, and a colorant, and an external additive layer coating the core, wherein the core is prepared such that it is extruded and extended to have a fiber phase, and is pulverized. The toner has an improved fixing ability to allow an electrostatic image to be fixed at a low temperature while having an excellent durability and an improved storage stability, while exhibiting reduced toner blocking and offset phenomena.
