Abstract
A method of manufacturing a toner including supplying a fluid containing a resin and a coloring agent to a retaining member including a film having multiple discharge orifices, discharging droplets of the fluid from the multiple discharge orifices at a speed of from 2 to 4 m/s by applying a pulse voltage having a trapezoid waveform to a piezoelectric body having a surface provided substantially parallel to the film to move the surface in a direction away from the film relative to a reference position of the surface followed by holding the surface there for a predetermined time, and bringing the surface back to the reference position; and solidifying droplets of the fluid discharged from the multiple discharge orifices to form mother particles.
