Abstract:
1. A toner-producing apparatus, comprising a liquid-discharging head and a particle forming unit configured to solidify liquid droplets, thereby forming particles, wherein the liquid-discharging head comprises: a reservoir suitable for a spray liquid, a nozzle plate comprising a plurality of nozzles suitable for discharging the spray liquid reserved in the reservoir, and a vibration generating unit comprising a vibrating surface facing the nozzle plate, wherein the reservoir is divided into a plurality of liquid chambers, wherein the vibration generating unit comprises elongated convex portions in a plurality of rows, the elongated convex portions comprising a piezoelectric element, wherein each of the liquid chambers corresponds to one of the elongated convex portions, wherein the apparatus is configured to produce particles by periodically discharging liquid droplets of the spray liquid from the nozzles and solidifying the liquid droplets, thereby forming particles with a ratio Dv/Dn of a volume average particle diameter Dv to a number average particle diameter Dn of less than 1.28, and wherein a number of nozzles facing one liquid chamber is from 2 to 200.
