The invention provdies an improved toner for electrostatic-charge image development and a method for producing a toner for electrostatic-charge image development. Toner particles in which the surfaces of core particles including a binder resin composed of a polyester resin are coated with shell layers. A shell layer is a resin composed of a copolymer of monomers including a monomer having a quaternary ammonium group and a (meth) acrylic monomer. The molar ratio of units derived from the monomer having a quaternary ammonium group in the copolymer is 5 mol % by mass or more and 35 mol % by mass or less. The toner for electrostatic-charge image development provided is has excellent heat-resistant storage stability, even if the toner is stirred in the developing unit for a long time, the toner can be charged at a desired charge value, so that fogging in the formed image can be suppressed. When the toner for electrostatic-charge image development is used, the occurrence of an image failure in the formed image such as color spot or fogging and degradation of the quality of the formed image due to adhesion of toner components onto the developing sleeve or photoconductor drum can be suppressed.
