Abstract:
A liquid developer containing toner particles containing a resin binder containing a polyester-based resin and a colorant, a dispersant, and an insulating liquid, wherein the dispersant contains a dispersant X having an adsorbing group having a nitrogen-containing group represented by the formula (I): wherein each of R 1 , R 2 , and R 3 , which may be identical or different, is an alkylene group having 1 or more carbon atoms and 22 or less carbon atoms, an alkenylene group having 2 or more carbon atoms and 22 or less carbon atoms, an alkynylene group having 2 or more carbon atoms and 22 or less carbon atoms, or an arylene group having 6 or more carbon atoms and 22 or less carbon atoms, and a dispersing group having a hydrocarbon group having a number-average molecular weight of 500 or more, and wherein the dispersant X has a mass ratio of the adsorbing group to the dispersing group (adsorbing group/dispersing group) of 1/99 or more and 42/58 or less, and a proportion of the dispersing group having a hydrocarbon group having a number-average molecular weight of 500 or more in all the dispersing groups of 55% by mass or more. The liquid developer of the present invention is suitably used in development or the like of latent images formed in, for example, electrophotography, electrostatic recording method, electrostatic printing method or the like.

Claim (Index 20):
The liquid developer according to  claim 1 , which is produced by a method comprising:\n (a) melt-kneading a resin binder comprising a polyester-based resin and a colorant, and pulverizing the mixture, to obtain toner particles; (b) adding a dispersant comprising a dispersant X to the toner particles obtained in (a), and dispersing the toner particles in an insulating liquid, to obtain a dispersion of toner particles; and (c) subjecting the dispersion of toner particles obtained in (b) to wet-milling to obtain a liquid developer.
