A toner for developing an electrostatic image comprises a binder resin and a dimer of a diarylguanidine type compound. The dimer is represented by the general formula (I) below:
wherein R¹, R², R³, R⁴, R⁵, R⁶, R¹a, R²a, R³a, R⁴a, R⁵a, and R⁶a are respectively a hydrogen atom, an alkyl group, an amino group, an alkoxy group, or an aryl group which may have a substituent, and may be the same with or different from each other; adjacent groups may be linked together to form a ring; and A is a linking group.
一种用于显影静电图像的调色剂由粘合剂树脂和二芳基胍类化合物的二聚体组成。二聚物由以下通式 (I) 表示:
其中 R¹、R²、R³、R⁴、R⁵、R⁶、R¹a、R²a、R³a、R⁴a、R⁵a 和 R⁶a 分别是氢原子、烷基、氨基、烷氧基或芳基,它们可以具有取代基,可以彼此相同或不同;相邻基团可连接在一起形成环;A 是连接基团。
