Abstract

Electrostatographic toners and developers containing (1,2-benzisothiazol-3-(2H)-ylidene 1,1-dioxide)acetate-terminated polymer charge-control agents are disclosed. The agents have the structure (I): ##STR1## wherein n can be as high as the number of hydroxyl groups in the polymer from which structure I is derived.
