摘要 |
A method of producing a liquid developer containing an insulation liquid and toner particles is provided. The method includes: grinding a toner material under the presence of a substance A in the insulation liquid; subjecting a dispersion liquid to a heat treatment at a higher temperature than a glass transition temperature of a resin material while giving shear force to the dispersion liquid: and mixing the dispersion liquid having been subjected to the heat treatment with a substance B. A liquid developer including an insulation liquid, toner particles, and a substance B is also provided. The toner particles are constituted of a substance A, a resin material and a coloring agent. The resin material is a polyester resin and/or a styrene-acrylic resin. The substance A is an acrylic modified silicone sufficiently soluble to the insulation liquid and the substance B is a silanol group-containing polysiloxane and/or a fluorine modified silicone. |
