Abstract: 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.

Abstract: A toner T1 develops an electrostatic latent image, the toner T1 having relieved charge-up characteristics, improved development characteristics, and improved transfer characteristics. The toner T1 may ensure high charge stability against environmental condition changes, and an appropriate amount of charges at a high printing speed, may reduce background contamination on a photoreceptor, may prevent undesirable fusing onto a blade even after prolonged printing, and may have high transfer efficiency and high image uniformity. The toner T1 may have effective flowability and transportability, and may have good storage stability, so as to be unlikely to cause blocking when stored for an extended time.
