Abstract
A pressure-fixable toner is produced by: dispersing or dissolving a mixture containing (a) a colorant and/or magnetic particles, (b) a pressure fixable binding material, and (c) a capsule wall-forming resin, in an organic solvent; dispersing the resulting dispersion or solution in a dispersion-stabilizing solution; heating the dispersion to evaporate off the solvent; dispersing the resulting encapsulated toner in a lower alcohol to remove the solvent remaining within the encapsulated toner; and thereafter drying the toner. The toner can be used to develop images in electrophotographic systems.
