Abstract
PURPOSE: To improve shelf life, the adhesiveness of the toner, etc. by using the toner comprising essentially the copolymer of the specific monomer which solvates with the carrier liquid of the liquid developer even before and after polymn., and other two kinds of monomers which do not solvent after polymn.
CONSTITUTION: The toner contg. copolymer of three kinds of monomer components A, B, C; the monomer component A, such as lauryl acrylate and vinyl stearate, expressed by the formula, the crosslinkable monomer component B such as polyfunctional (meth)acrylate, the monomer component C from unsaturated carboxylic acid (anhydride), unsaturated nitrogen-contg. compound (vinyl pyridine, cyanoethyl acrylate, etc.), glycidyl group-contg. unsaturated compound (meth)acrylate, is dispersed in carrier liquid of petroleum aliphatic hydrocarbon or halogenated aliphatic hydrocarbon, whereby the developer is prepd. Since the component A has the property of solvating even after polymn., the toner particles have good dispersion stability in the solvent. The component C is polar and improves the polarity, dispersion stability and adhesiveness to transfer paper of the toner.
