Abstract
An electrophotographic liquid developer includes a carrier liquid and toner particles. The toner particles include a colorant and a resin component and are dispersed in the carrier liquid. The resin component includes a polyester resin as a main component. When 0.3 g of the liquid developer is dropped on a filter paper (which is defined in JIS P 3801) from a point of 10 mm height, the carrier liquid diffuses in the filter paper at a speed not lower than 1 mm/minute.
