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), Rto Reach independently represent a hydrogen atom, a hydroxy group or an organic group. At least one of Rand Ror at least one of Rand Rrepresents a hydroxy group.
