Main performances of a toner are significantly affected by a shape and surface characteristics of toner particles. Using an external additive may be a factor that complicates control of surface characteristics of the toner particles, and anti-offset properties of toner change according to a wax and a binder composition at a surface portion of the toner particles. Provided is a toner usable in electrophotography, wherein the toner has improved durability, fixability, charging stability, and cleaning properties through an appropriate distribution of a binder, a wax, and an external additive on a surface portion of toner particles.
