    • The production process is a process for producing a toner for electrostatic image development. The process has an aggregating step of adding an aggregating agent composed of a compound having a divalent or trivalent metal element into a dispersion with fine particles of a binder resin dispersed in an aqueous medium, and an aggregation terminating step of adding an aggregation terminating agent into the dispersion. The aggregation terminating agent is composed of a compound having at least one of a structure (1) represented by a formula (1) and a structure (2) represented by a formula (2). In the formulae (1) and (2), R1 to R9 each independently represent a hydrogen atom, a hydroxy group or an organic group. At least one of R1 and R4 or at least one of R5 and R6 represents a hydroxy group.
    • 生产过程是用于生产用于静电图像显影的调色剂的方法。 该方法具有聚集步骤,将由具有二价或三价金属元素的化合物组成的聚集剂添加到分散于分散于水性介质中的粘合剂树脂的细颗粒的分散体中,以及聚集终止步骤,将聚集终止剂加入 分散体。 聚集终止剂由具有由式(1)表示的结构(1)和由式(2)表示的结构(2))中的至少一种的化合物组成。 在式(1)和(2)中,R 1至R 9各自独立地表示氢原子,羟基或有机基团。 R 1和R 4中的至少一个或R 5和R 6中的至少一个表示羟基。
