ABSTRACT:
An electrophotographic toner having polymeric binder and a charge control agent selected from the group consisting of sulfonamides having the general structure: ##STR1## Each R.sup.1 is independently O, S, N--H, N--R.sup.z, or N--L--R.sup.z ; where L is a linking group selected from: ##STR2## and R.sup.z is independently selected from the group consisting of alkyl having from 1 to 20 carbons, cycloalkyl having from 3 to 18 carbons, and aromatic and heteroaromatic ring systems having a solitary ring or 2 to 3 linked or fused rings. R.sup.a, R.sup.b, and R.sup.c are each independently a ring system of a single ring or 2 or 3 fused or linked rings, said ring system having from 3 to 34 carbons, including substituent carbons. d is an integer from 0 to 3. e is an integer from 0 to 3. The sum of d+e is 2 or 3.
