A liquid developer comprised of toner particles having excellent fixing properties to a recording medium is provided, and a liquid developer in which toner particles having uniform shape and small particle size distribution are dispersed is also provided, and further a method of producing a liquid developer capable of producing such a liquid developer efficiently is also provided. In particular, a producing method capable of producing such a liquid developer as described above in a method harmless to the environment is provided. The liquid developer producing method is a method for producing a liquid developer which is comprised of an insulation liquid and toner particles dispersed in the insulation liquid and is characterized by comprising the steps of: a water-based dispersion liquid preparing step for preparing a water-based dispersion liquid, the water-based dispersion liquid comprising a dispersoid comprised of a material containing a resin material and a water-based dispersion medium constituted from a water-based liquid in which the dispersoid is dispersed; a dispersion medium removal step for removing the dispersion medium to obtain toner particles; and a dispersing step for dispersing the toner particles into the insulation liquid.
A method of producing a liquid developer which comprises an insulation liquid and toner particles dispersed in the insulation liquid, the method comprising the steps of:
The method of producing a liquid developer as claimed in claim, wherein the toner particles obtained in the water-based dispersion medium removal step are directly dispersed in the insulation liquid without intervening any step of collecting the obtained toner particles between the dispersin medium removal step and the dispersing step.
