Method for producing toner for developing electrostatic image and apparatus for producing resin particles

A method for producing a toner for developing an electrostatic image, comprising:

• ejecting a solution or dispersion liquid in the form of droplets from a droplet ejecting unit having a plurality of holes provided in a part of a flow channel for feeding the solution or dispersion liquid, the solution or dispersion liquid comprising a solvent and a toner material containing at least a binder resin and a pigment, dissolved or dispersed in the solvent, wherein a plurality of the droplet ejecting units are arranged in a side wall of the chamber to eject droplets toward the center of the chamber, and wherein at least a portion of the liquid containing at least the binder resin and pigment fed from a liquid container to the droplet ejecting unit is circulated between the liquid container and the droplet ejecting unit and back to the liquid container;
• and
• drying and solidifying the ejected droplets so as to obtain a toner, while the ejected droplets are transported by a primary transport air flow flowing in the direction in which the droplets are ejected,
• wherein the ejected droplets are further transported by a secondary transport air flow which transports the ejected droplets in a different direction from a direction in which the primary transport air flow flows, wherein the secondary transport air flow flows from upside to downside, and
• wherein a smaller angle of angles formed between a velocity vector of the primary transport air flow and a velocity vector of the secondary transport air flow is less than 120 degrees.
