ABSTRACT:
An electrophotographic toner having polymeric binder and a charge control agent selected from the group consisting of sulfonamides having the general structure: ##STR1## and metal salts thereof. T.sup.1 is independently selected from H, 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.1 is O, S, N--H, N--R.sup.5, or N--L--R.sup.5 ; where L is a linking group selected from: ##STR2## and R.sup.5 is independently selected from 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. L.sup.1 and L.sup.2 are each independently a direct link or divalent alkyl or fluoroalkyl having from 1 to 20 carbons. R.sup.a and R.sup.b are each independently selected from the group consisting of H, F and ring systems having a solitary ring or from 2 to 3 fused or linked rings, said ring system having from 3 to 34 carbons, including carbons of substituent groups. If L.sup.1 is a direct link, R.sup.a is a ring system and if L.sup.2 is a direct link, R.sup.b is a ring system.
