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

A preparing method of an electrostatic charge image developing toner, the method comprising:

• aggregating at least binder resin particles and release agent particles contained in a dispersion to form aggregated particles;
• heating and coalescing the aggregated particles to form coalesced particles;
• and
• filtering and cleaning the coalesced particles to obtain toner particles, wherein before the aggregating or during the aggregating, a polymer dispersant is added to the dispersion in an amount of 0.01% by weight or more and 1.3% by weight or less with respect to a total weight of the obtained toner particles,
• the polymer dispersant is added to the dispersion as an aqueous solution comprising 1% by weight to 40% by weight of the polymer dispersant,
• the aqueous solution comprises 5% by weight or more and 40% by weight or less of the polymer dispersant, and
• the polymer dispersant is at least one compound selected from the group consisting of a formalin condensate sulfonate, a salt of an α-olefin-maleic acid copolymer, and a salt of a styrene-maleic acid copolymer.
