PROBLEM TO BE SOLVED: To provide toner for electrophotography which is improved in image storing property and toner storing property without impairing low-temperature fixability, and to provide its manufacturing method, an electrostatically charged image developer, and an image forming method. SOLUTION: The toner for electrophotography having a core shell structure is characterized in that binding resin is crystalline polyester resin alone or mixed resin of the crystalline polyester resin and amorphous macromolecules (B), toner mother particles contain 10 to 40 mass% resin (A) of 60 to 100°C in glass transition temperature, 1,000 to 5,000 in weight average molecular weight, and 1.0 to 1.3 in weight average molecular weight/number average molecular weight (Mw/Mn) and have their surfaces coated with amorphous macromolecules (C) as a shell, or toner which has a core shell structure and characterized in that the toner mother particle surfaces are coated with surface layers containing a norbornene-based polymer, its manufacturing method, the electrostatically charged image developer, and image forming apparatus.
