Preparing method of electrostatic charge image developing toner, electrostatic charge image developing toner, and electrostatic charge image developer

Abstract

A preparing method of an electrostatic charge image developing toner includes: aggregating binder resin particles in a dispersion containing the binder resin particles to form aggregated particles; and coalescing the aggregated particles by heating a dispersion containing the aggregated particles to form toner particles, in which the aggregating includes adding a divalent or higher valent metal salt compound to the dispersion containing the binder resin particles, and the preparing method satisfies the following Requirement (1), Requirement (1): a ratio M/S of a total metal ion amount M (mol) generated from the divalent or higher valent metal salt compound to a total surface area S (m2) of the binder resin particles at a start of the aggregating is 1.5×1010 or more and 2.5×1013 or less.
