    Abstract: An electrostatic toner contains a polymeric binder and as a charge stabilizer a polyamine whose average molecular weight is from 150 to 15,000 and wherein the nitrogen atoms are separated from each other by C1-C13- alkylene, which may be phenyl-substituted, or by phenylene, which may be C1-C4-alkyl-substituted, and are substituted by C1-C13-alkyl, which may be phenyl-, hydroxyl- or carboxyl-substituted, phenyl, C1-C10-alkanoyl, benzoyl, C1- C6- alkylcarbamoyl, phenylcarbamoyl or a radical of the formula CO-L-CO, where L is C2-C8-alkylene, the last case resulting in the crosslinking of two polyamine units.
