Abstract
An insulating developer composition comprised of resin particles, pigment particles, wax component particles, compatibilizer, and a surface additive mixture comprised of metal salts of fatty acids, silica particles, and metal oxide particles; and carrier particles comprised of a ferrite core with a polymer coating or mixture of polymer coatings; and wherein said developer is of a conductivity of from about 10.sup.-14 to about 10.sup.-16 (ohm-cm).sup.-1.
Claims36
An insulative developer composition consisting essentially of resin particles, pigment particles, low molecular weight with a weight average molecular weight of from about 1,000 to about 20,000, wax component particles, compatibilizer, and a surface additive mixture comprised of from about 0.1 to about 0.8 weight percent in each instance of metal salts of fatty acids, silica particles and metal oxide particles;
- and carrier particles comprised of a ferrite core with a polymer coating or mixture of polymer coatings;
- and wherein said coating or coatings contains a conductive component, and wherein said developer is of a conductivity of from about 10.sup.-14 to about 10.sup.-16 (ohm-cm).sup.-1.
