ABSTRACT:
Dry toners for use in electrostatic latent image development comprising a colorant in a resin binder are described, wherein said resin binder comprises a polyester containing --COOH groups in which at least one of the --COOH groups is replaced with nitrogen-containing compounds such as amines, ammonium salts, betaines, pyridinium salts, and azines. These toners are superior in development of negatively charged latent images and exhibit good low temperature fixability.
