A guanidine type compound has the following formula:
wherein R¹ to R⁸ are each a hydrogen atom, an alkyl group, an amino group, an alkoxy group, a substituted or unsubstituted aryl group, and R¹ to R⁸ may be the same as or different from each other and together may form a ring with the adjacent substituents; X is a halogen atom, a hydroxyl group or an alkoxy group; and m and n are each an integer having a value of 1 to 8. The guanidine compound is employed in a toner for electrostatic development and the toner can be used in an electrophotographic apparatus including a facsimile apparatus for receiving image information from an electrophotographic copier.
一种胍类化合物具有下式:
其中 R¹ 至 R⁸ 各为氢原子、烷基、氨基、烷氧基、取代或未取代的芳基,且 R¹ 至 R⁸ 可彼此相同或不同,并可与相邻取代基共同形成环;X 为卤素原子、羟基或烷氧基;以及 m 和 n 各为数值为 1 至 8 的整数。胍基化合物可用于静电显影的调色剂中,该调色剂可用于电子照相设备中,包括从电子照相复印机接收图像信息的传真设备。
