Disclosed are pigment composite particles which are superior in water resistance, weather resistance, thermal stability and hardness. The pigment composite particles are prepared by suspension-polymerizing an aqueous suspension comprising (a) a pigment paste comprising pigment and a pigment grinding resin having a hydrophilic group of at least 0.2 mmol/g, (b) a polymerizable monomer and (c) a polymerization initiator.

An encapsulated toner composition comprised of a core comprised of a polymer binder and pigment, encapsulated in a shell derived from the polycondensation of a polyisocyanate and amino acid with an amide or hydroxy functionality.

An encapsulated toner composition comprised of a core comprised of a monomer, or monomers which are subsequently polymerized; pigment or dye particles; an emulsifier component selected from the group consisting of organic methyl cellulose and hydroxylated methyl cellulose components into which the pigmented monomer mixture is dispersed, and wherein the core is encapsulated within a polymeric shell.

A method of forming fixed images includes charging a photoconductor; exposing the photoconductor to light; developing an electrostatic latent image, such that a toner is applied to the electrostatic latent image formed on a transfer film moving in partially close contact with the photoconductor to form a visible image; transferring the formed visible image onto a recording medium such as a recording paper; and fixing the transferred visible image onto the recording medium. The toner is an encapsulated toner, the photoconductor is a heat-resistant photoconductor, and the transfer process and the fixing process are simultaneously carried out on the surface of the heat-resistant photoconductor covered with the transfer film onto the preheated recording medium.

An ionographic process which comprises the generation of an image comprised of characters, and developing the image with a toner mixture comprised of an encapsulated toner and a toner free of encapsulation.
