ABSTRACT:
A toner in which at least a major portion of the resin component is a soft polymer encapsulated and dispersed in a tough polymer matrix in a plurality of discrete domains, instead of as a single core. A convenient method of providing such dispersion is by the use of a block, graft or shaded copolymer, as a dispersing agent, comprised of components which are identical to the soft and tough polymers. The toner is pressure fixable.
