发明名称 PROCESS FOR PRODUCING LIQUID DEVELOPING AGENT, AND LIQUID DEVELOPING AGENT
摘要 A liquid developer which includes toner particles having small particle size distribution, uniform shape, and excellent fixing properties to a recording medium is provided, a liquid developer which includes toner particles having small particle size distribution and uniform shape and being capable of exhibiting a property of each of materials constituting the toner particles sufficiently is also provided, and a liquid developer having excellent anti-offset properties (mold release properties) 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 of the present invention includes the steps of: preparing a water-based dispersion liquid comprising a dispersoid composed 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; removing the water-based dispersion medium by spraying the water-based dispersion liquid in the form of droplets to obtain toner particles, each of the toner particles being formed by aggregation of a plurality of particles of the dispersoid contained in each droplet of the water-based dispersion liquid; and dispersing the toner particles into the insulation liquid directly.
