Toner for electrostatic-charge image development and method for producing toner for electrostatic-charge image development
Abstract:
A toner for electrostatic-charge image development contains toner particles in which the surfaces of core particles, including a binder resin composed of a polyester resin, are coated with shell layers. The shell layer is formed of a resin composed of a copolymer of monomers including a monomer having a quaternary ammonium group and a (meth)acrylic copolymer. The molar ratio of units derived from a monomer having a quaternary ammonium group is 5 mol % or more and 35 mol % or less.
