Abstract: The toner for electrostatic image development has excellent charge properties, by which excellent toner particle size-controlling ability is achieved, and moreover the sharpening of a particle size distribution is achieved. The toner is composed of toner particles containing a binder resin. The process has an aggregating step of adding an aggregating agent containing a transition element into an aqueous medium of dispersed fine binder resin particles to aggregate the fine binder resin particles, and an aggregation-stopping step of adding an aggregation stopper composed on a sulfur atom-containing compound exhibiting a reducing action on the aggregating agent. The aggregating agent is a salt of a bivalent or higher metal selected from Sr, Ti, V, Cr, Mn, Fe, Co, Ni and Cu.

Abstract: 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.
