Abstract:
A toner for electrostatic use includes a binder resin including an amorphous polyester resin having a urethane bond and a crystalline polyester resin, a metal ion forming a chemical bond with the binder resin, at least one colorant forming a coordinate bond with the metal ion and being supported on the binder resin through the metal ion, and at least three elements selected from an iron element, a silicon element, a sulfur element, and a fluorine element while including at least one of an iron element, a silicon element, and a sulfur element, wherein an amount of the iron element is about 1000 ppm to about 10000 ppm as an element concentration, an amount of the silicon element is about 1000 ppm to about 5000 ppm as an element concentration, and an amount of the sulfur element is about 500 ppm to about 3000 ppm as an element concentration.
