PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that can provide both low-temperature fixability and long-term storage stability, and a manufacturing method of the same.SOLUTION: A toner for electrostatic charge image development is composed of toner particles that contain a binder resin and have a volume reference median diameter of 3 to 8 μm, and the toner particles have a core-shell structure composed of core particles that have a domain composed of an amorphous resin dispersed in a matrix composed of a crystalline resin and a shell layer composed of the amorphous resin that covers each of the core particles. An average particle diameter of the core particles is 2.5 to 5.0 μm; a mass ratio of the crystalline resin and amorphous resin (crystalline resin:amorphous resin) in the core particles is 55:45 to 90:10; a thickness of the shell layer is 0.5 to 2.0 μm; a content ratio of the sum of the amorphous resin contained in the core particles and the amorphous resin constituting the shell layer in the binder resin is 70 to 95 mass%. |
