sulfoisophthalate); and carrier particles.
19. A method of imaging consisting essentially of formulating an electrostatic
latent image on a photoreceptor, affecting development thereof with a toner composition
comprised of resin particles, pigment and a charge enhancing additive comprised of a
polymer of resin particles with a charge enhancing moiety chemically attached thereto, and
which charge additive is selected from the group consisting of poly(1,2-propylene-sodio 5-
sulfoisophthalate), poly(1,2-propylene-calcio 5-sulfoisophthalate), poly (1,2-propylene-
tetralkylammonium 5-sulfoisophthalate), poly(ethylene-sodio 5-sulfoisophthalate),
poly(ethylene-calcio 5-sulfoisophthalate), poly(ethylene-dimethyldistearylammonio 5-
sulfoisophthalate), copoly(1,2-propylene-diethylene sodio-5-sulfoisophthalate), copoly(1,2-
propylene-diethylene calcio-5-sulfoisophthalate), and copoly(1,2-propylene-diethylene
dimethyldistearylammonio-5-sulfoisophthalate); and thereafter transferring the developed
image to a suitable substrate.
