A novel method of particle formation by which aggregated latex particles extremely reduced in the content of fine particles and coarse particles and satisfactory in powder properties including blocking resistance and powder flowability can be recovered from a polymer latex without deteriorating the original quality possessed by the polymer itself. The process for producing aggregated latex particles is characterized in that a polymer latex containing a water-soluble polymer having the property of forming a physical gel is atomized or dropped in a gas phase containing an inorganic salt and/or an acid in an aerosol state and the droplets of the polymer latex are caused to fall or come into an aqueous phase.
