A toner for electrostatic-image development comprising color resin particle containing a binder resin, a colorant, a charge control agent, and a thickener,
- wherein the binder resin is a copolymer including styrene monomer unit and (meth)acrylate monomer unit,
- the content of the thickener is 0.2 to 5.0 parts by mass relative to 100 parts by mass of the binder resin,
- the thickener is a resin containing a nitrogen atom, and the content of nitrogen atom is 150 to 1500 mass ppm in the toner for electrostatic-image development.
A toner for electrostatic-image development comprising color resin particle containing a binder resin, a colorant, and a charge control agent,
- wherein the binder resin is a copolymer including styrene monomer unit and (meth)acrylate monomer unit, the copolymer is cross-linked with a cross-linking agent, the cross-linking agent contains a cross-linkable resin, the cross-linkable resin is a resin containing a nitrogen atom,
- the content of the cross-linking agent is 0.3 to 5.0 parts by mass relative to 100 parts by mass of the binder resin, and
- the content of nitrogen atom is 150 to 1500 mass ppm in the toner for electrostatic-image development.
