Abstract
A method of manufacturing toner is provided, including discharging a toner constituents liquid from multiple nozzles to form liquid droplets and solidifying the liquid droplets into toner particles. The multiple nozzles satisfy the following formula: 2.5≦p/d≦7.5 wherein d represents an outlet diameter of each nozzle and p represents an interval between two nozzles.

A method of manufacturing toner, comprising:
- discharging a toner constituents liquid from multiple nozzles to form liquid droplets;
- and
- solidifying the liquid droplets into toner particles,
- the multiple nozzles satisfying the following formula:
- 2.5≦p/d ≦7.5
- wherein d represents an outlet diameter of each nozzle and p represents an interval between two nozzles,
- the discharging further comprising:
- vibrating the toner constituents liquid in a liquid column resonance liquid chamber having the multiple nozzles so that a standing wave is formed by liquid column resonance and,
- the multiple nozzles being formed in a region including an antinode of the standing wave.
