Abstract
An electrophotographic toner composition comprising toner particles composed of a binder resin and a colorant and fine particles adhered to the surface of the toner particles is disclosed, in which said fine particles are zinc oxide fine particles having an average particle size of from 2 to 100 nm and having been surface-treated with a silane coupling agent or a silicone oil. The toner composition is excellent in charging properties, such as chargeability, environmental stability of chargeability, and toner admixing properties.
