ABSTRACT:
The present invention provides a method for producing a toner, which produces a toner by using a dispersion comprising a dispersion medium having finely dispersed therein a dispersoid containing a raw material for the production of a toner, the method comprising intermittently ejecting the dispersion from a head unit by applying an ejection energy, and solidifying it into a particulate form while transporting the ejected dispersion through a solidification unit by an air flow. The ejection energy may be applied in the form of pressure pulse, or may be applied by the volume change of a bubble. Also disclosed are a toner obtained by the method, and an apparatus for performing the method.
