| 发明名称 | Toner for electrostatic image development | ||
| 摘要 | A toner for electrostatic image development having sufficient low-temperature fixing properties, and excellent heat resistant storage stability and crush resistance is provided. In toner particles containing at least a binder resin, the binder resin contains a polymer having a structural unit represented by a general formula (1), wherein R1, R2, and R3 each independently represent a hydrogen atom, a hydroxyl group, or an alkoxy group, or two adjacent groups of R1, R2, and R3 combine to form —O(CH2)iO—, where i represents an integer of 1 or 2, provided that at least one of R1, R2, and R3 is an alkoxy group, or two adjacent groups combine to form —O(CH2)iO—; and R4 represents a hydrogen atom, a halogen atom, an alkyl group, a hydroxyl group, or an alkoxy group.; | ||
