Abstract
A method for manufacturing a toner, including: dissolving or dispersing toner constituents including a resin, a colorant, a release agent, and a graft polymer including a polyolefin resin unit and a vinyl resin unit in a solvent, to prepare a toner constituent liquid; supplying the toner constituent liquid to a retention part configured to retain the toner constituent liquid; discharging the toner constituent liquid from the retention part to a granulation space through plural holes arranged on the retention part, while exciting the toner constituent liquid by a vibration means in contact with a part of the retention part, so that the discharged columnar toner constituent liquid is constricted to form liquid droplets; and converting the liquid droplets into solid toner particles; together with a toner manufactured by the above method.
