PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development, which gives low-temperature fixability and heat-resistant storage property, suppresses glossiness to a low level of an image formed of the toner, and has enough printing durability to form images with good picture qualities for a long period of time.SOLUTION: The toner for electrostatic charge image development comprises toner particles having a core-shell structure composed of a core particle made of a vinyl resin and a shell layer covering the core particle and made of a non-crystalline resin in which a vinyl polymerization segment and a polyester polymerization segment are bonded. The non-crystalline resin has a glass transition temperature of 50 to 75°C. A content percentage of the vinyl polymerization segment in the non-crystalline resin is 1 to 25 mass%. In a chromatogram showing a molecular weight distribution of the non-crystalline resin by gel permeation chromatography (GPC), a ratio of a resin component having a molecular weight of 100000 or more is 1 to 20% by area. |
