To provide, as a toner manufacturing method based on the injection granulation method, a high-productivity manufacturing method of a toner for electrostatically charged image development capable of preventing toner adhesions to wall surfaces and concomitant coalescence of yet-to-be-solidified particles and accordingly having a sharp particle diameter distribution yielding a favorable image quality.
The provided manufacturing method of particles is comprising a droplet discharge step of discharging, as droplets, a particle composition liquid from at least one discharge orifice and a solidification step of solidifying the droplets, wherein the respective steps are executed within a container 61, walls of the container are at least partially constituted by air-permeable walls, and air flows streaming into the container from outside the container via the air-permeable walls are generated at the solidification step.
