PURPOSE:To obtain a toner for liquid development giving a clear picture having the good dispersion stability and fixing property, by coating an org. or inorg. coloring pigment by a mixture of a high polymer substance which is insoluble or hardly soluble in a carrier solvent of a liquid developing agent and wax. CONSTITUTION:An org. or inorg. pigment is dispersed in the mixture having the weight ratio of 5:95-95:5 in which a high polymer substance (epoxy resin and polyester resin etc.) insoluble or hardly soluble in an aliphatic hydrocarbon or a halogenated hydrocarbon having high insulating property and low dielectric constant of a liquid developer and wax (low molecular weight polyolefin, paraffin wax, chlorinated paraffin and low molecular weight polyethylene oxide etc.) are mixed, to prepare a toner, and this toner is used as a toner of a liquid developer for electrostatic photography. By using this toner which is well dispersed in the liquid developer and which is not separated and sedimentated during preservation, a picture having a good fixing property and high resolution is obtained. |
