摘要:
To provide a method including processing electrophotographic toner constituent material to a fibrous fine precursor and pulverizing and cutting it to obtain a uniform fibrous toner with energy efficiency in an apparatus for producing electrophotographic toner including a nozzle unit containing a nozzle having a flow path tapering toward the nozzle hole at 2° to 20° and a gas nozzle unit containing a gas nozzle and gas flow path tapering toward the nozzle hole at 15° to 33° relative to a direction of a nozzle axis, wherein the toner constituent material containing a raw material A containing a resin and pigment, and a raw material B containing one of a low melting point resin, wax and organic solvent, is extruded from the nozzle at 150° C. to 320° C., and drawn by gas flow from the gas nozzles so as to be a fibrous fluid while controlling the flow rate.
