    摘要: Disclosed is a liquid developer composition comprising a liquid vehicle, a charge control additive, and toner particles containing pigment particles and a resin selected from the group consisting of polyolefins, halogenated polyolefins, and mixtures thereof. Preferred resins include poly-.alpha.-olefins and chlorinated polypropylenes. The resin is soluble in the liquid vehicle at elevated temperatures and insoluble in the liquid vehicle at ambient temperatures. Also disclosed is a liquid developer composition comprising a liquid vehicle, pigment particles, a charge control additive, and a resin selected from the group consisting of polyolefins, halogenated polyolefins, and mixtures thereof, wherein the resin is soluble in the liquid vehicle at elevated temperatures and insoluble in the liquid vehicle at ambient temperatures, and wherein the liquid developer is prepared by dissolving the resin in the liquid vehicle at temperatures of from about 80.degree. C. to about 120.degree. C., subsequently adding the pigment particles to the resulting solution, attriting the resulting mixture for from about 20 minutes to about 75 minutes, cooling the mixture to ambient temperature over a period of from about 1 hour to about 3 hours with continuous mixing, and subsequently adding to the mixture the charge control additive.
