This invention is directed to an improved cold pressure flexible toner composition comprised of a blend of two immiscible polymers selected from the group consisting of (1) a polymer of polystyene-co-stearylmethacrylate as a hard component, and poly[octadecyl vinyl ether-co-maleic anhydride] as a soft component, and (2) polyisobutylmethacrylate composition as a hard component, and poly[octadecyl vinyl ether-co-maleic anhydride], as a soft component, the soft component being present in an amount of from about 35 percent by weight to about 75 percent by weight, and the hard component being present in an amount of from about 25 weight percent to about 65 weight percent; and the use of such compositions for developing images in electrostatographic imaging systems.
