Abstract
An improved positively charged developer compositions comprised of toner compositions containing resin particles, pigment particles and modified charge enhancing additives comprised of flow aid compositions having chemically bonded thereto, or chemiadsorbed on the surface thereof amino alcohol derivatives comprising at least one hydroxyl group, and at least one amino substituent selected from the group consisting of primary amines, secondary amines, and tertiary amines; and carrier particles.
Claims27
A positively charged developer composition comprising carrier particles and a toner composition containing resin particles, pigment particles, and modified charge enhancing additives comprising flow aid compositions having chemically bonded thereto, or chemiadsorbed onto the surface thereof, amino alcohol derivatives of the formula ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 are substituents independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, phenyl, naphthyl, substituted phenyl, substituted naphthyl, amino, heterocyclic components containing nitrogen, oxygen, or sulfur;
- unsaturated substituents;
- and aliphatic cyclic substituents, subject to the provision that at least one of the R.sub.1, R.sub.2 or R.sub.3 substituents comprise a hydroxyl group.
