Abstract

An electrostatographic toner material suitably employable for the pressure fixing process, which comprises encapsulated toner particles having an average particle size in the range from about 0.5 to 1,000 microns, in which the toner particle comprises a pressure fixable adhesive core material containing a colorant and a curable substance and a pressure rupturable shell enclosing the core material, the outer surface of the shell being provided with a curing agent capable of curing said curable substance. The curable substance and the curing agent can be separately incorporated into the core materials of the different encapsulated toner particles.
