Toner for electrostatic image development, production method of the toner and image formation method |
摘要 |
The present invention provides a toner for electrostatic image development that suppresses the fluctuation of electrostatic charge amount in accordance with environmental fluctuation and has good color reproducibility (wide color gamut), a producing method of the toner, and an image forming method using the toner for electrostatic image development. The toner for electrostatic image development of the invention includes a toner particle that contains at least a binder resin. The toner particle includes a polymer having a structural unit represented by a following general formula (1) as the binder resin.;
where R1 represents a hydrogen atom or substituted or unsubstituted C1-C2 alkyl group, A represents an oxygen atom or divalent linking group, B represents a hydrogen atom, substituted or unsubstituted C1-C4 alkyl group, aldehyde group, carboxy group or hydroxy group, and X represents an oxygen atom, nitrogen atom or sulfur atom. |
