PROBLEM TO BE SOLVED: To provide a method for producing a toner which ensures no or very small range of variation due to particles in various property values required for a toner and is used in a developer for developing an electrostatic charge image in electrophotography, electrostatic recording, electrostatic printing or the like, a toner produced by the method and an apparatus for producing a toner using the method. SOLUTION: The method for producing the toner includes ejecting a toner composition fluid containing a toner composition which contains at least a resin and a colorant, from a nozzle vibrated at a constant frequency to make the toner composition fluid into droplets, and solidifying the droplets to be made into particles. Alternatively, the method for producing the toner includes ejecting a solution or dispersion of a material for a toner containing at least a resin and a colorant, from a nozzle vibrated at a constant frequency to make the solution or dispersion into droplets, and drying the droplets. The method preferably uses a vibration producing means to vibrate the nozzle. It is preferable that the vibration producing means and the nozzle get contact with each other and the nozzle is directly vibrated by the vibration producing means. COPYRIGHT: (C)2007,JPO&INPIT
