CHARGE-CONTROL AGENT COMPOSITION AND TONER CONTAINING THIS COMPOSITION

摘要

A toner for electrophotography having improved characteristics, is prepared by mixing carbon or by mixing carbon with a charge-control agent in a solvent. The charge-control agent and carbon are uniformly dispersed, and hence the charge-control agent composition exhibits excellent dispersiblility to resin. A toner containing this composition is free from charging-instability and scattering, and provides a clear developed image.
