Claim 11:
12. The method for producing a toner for electrostatic charge image development according to claim 1, the method further comprising:
before terminating the growth of the aggregated particles, mixing the dispersion containing the aggregated particles and a dispersion containing shell layer-forming resin particles that will form a shell layer, and aggregating the shell layer-forming resin particles on the surfaces of the aggregated particles to form second aggregated particles,
wherein terminating the growth of the aggregated particles involves terminating growth of the second aggregated particles by adding an alkaline aqueous solution to a dispersion containing the second aggregated particles to increase a pH of the dispersion containing the second aggregated particles,
fusing and coalescing the aggregated particles involves fusing and coalescing the second aggregated particles into toner particles by heating the dispersion containing the second aggregated particles, and
terminating the growth of the aggregated particles includes, while stirring the dispersion containing the second aggregated particles, stepwise or continuously reducing a stirring power per unit volume.
