发明名称 Electrostatic-image developing toner, electrostatic image developer, and toner cartridge
摘要 An electrostatic-image developing toner contains toner particles. The toner particles contain a binder resin, a release agent, and a styrene-(meth)acrylic resin. The binder resin contains a polyester resin. About 70% or more of all release agent is present within about 800 nm from surfaces of the toner particles. The styrene-(meth)acrylic resin is present in an amount of about 5 to about 25 atomic percent of the resin components in the surfaces of the toner particles as determined by X-ray photoelectron spectroscopy (XPS).
