摘要：
Toner compositions comprising resin particles, pigment particles, and as a charge enhancing additive inner salts wherein the negative charge center is covalently attached to the positive charge center. Also disclosed are developer compositions comprising the aforementioned toner components and carrier particles, which compositions are particularly useful for the development of electrostatic latent images. Additionally, there can be selected for the toner and developer compositions mixtures of charge enhancing additives including mixtures of the aforementioned inner salts and second charge enhancing additives such as quaternary ammonium compounds.
