To provide a toner for developing an electrostatic image capable of satisfying three characteristics of charging property, low-temperature fixing property, and cleaning property at a high level. A binder layer comprising at least a crystalline polyester resin and an amorphous polymer, comprising a continuous matrix, the core layer containing the crystalline polyester resin, and completely covering the core layer, the amorphous An electrostatic charge image developing toner comprising a shell layer containing a polymer, wherein the average value of the shape factor SF1 defined by the following formula (1) is 110 or more: . Formula (1) SF1 = (absolute maximum length of toner diameter) 2 / projection area of toner) × (π / 4) × 100 [Selection figure] None |
