Abstract: There is provided a toner for electrostatic-image development that can obtain low-temperature fixing property, heat-resistant storability and long-term stability of charging while having excellent low-temperature fixing property.A toner for electrostatic-image development is formed with toner particles containing a binder resin and a crystalline ester compound, the crystalline ester compound has a linear-chain structure, and the binder resin contains a styrene-acrylic resin including a structural unit derived from an acrylic ester monomer represented by general formula (1) below. Meanwhile, in the general formula (1), R1 represents a hydrogen atom or a methyl group, and R2 represents a hydrogen atom, an alkyl group having 1 to 16 carbon atoms or an aryl group having 6 to 15 carbon atoms. m represents 2 or 3, and n represents an integer of 1 to 25.
