Abstract:
1. A method of manufacturing a liquid developer, the method comprising: forming a water-based emulsion by dispersing a dispersoid mainly containing a resin material in a water-based liquid; forming associated particles having an average particle size of 1˜10 μm by adding an electrolyte to the water-based emulsion and associating the dispersoid having an average particle size of 0.01˜3 μm in the water-based emulsion; obtaining the associated particles by drying the dispersoid; mixing the associated particles with a first insulation liquid; disintegrating the associated particles in the first insulation liquid so as to obtain toner particles having an average particle size of 1˜5 μm; and adding a second insulation liquid that is different from the first insulation liquid.
