ABSTRACT:
This invention is directed to dry, negatively charged toner compositions and developer compositions, the toner composition being comprised of resin particles prepared from a polyester having a glass transition temperature of 50.degree. to 100.degree. C. and a weight average molecular weight of 20,000 to 100,000 and from about 0.1 to about 10 percent by weight based on the weight of the resin particles of a mixture of ortho-benzoic sulfimide as represented by the formula: ##STR1## and para-anisic acid as represented by the formula: ##STR2## in a weight ratio of 1:1 as a charge-controlling additive.
