    摘要： A liquid developer for use in electrophotography is disclosed, which comprises (i) a toner comprising as the main toner components a colorant, a resin, and a polyolefin resin having an acid value of from 5 to 50 and a melt viscosity at 200.degree. C. of from 100 to 15,000 cps, and (ii) a carrier liquid in which the toner is dispersed. The polyolefin resin and the colorant in the liquid developer may constitute an integral flushing colorant which is prepared by subjecting the resin and the colorant to flushing processing.
