摘要： There is provided a toner for a two-component type developer, which comprises (i) toner particles comprising a fixing resin having anionic polar groups, a coloring agent, and a magnetic powder which is used in an amount of 0.1 to 5 parts by weight for 100 parts by weight of the fixing resin, and (ii) an additive comprising silica, alumina and titania, and being adhered on surfaces of the toner particles in a total amount of 0.15 to 2 parts by weight for 100 parts by weight of the toner particles, and contains substantially no charge control agent. The toner exhibits a stable chargeability during a long-term use without generation of a spent toner. As a result, the toner suppresses the image fogging and the toner scattering, and ensures a stable image density and a high image quality for a long term.

摘要： An electrophotographic developer comprising a toner and a carrier, in which the carrier is provided on the surface of a core material thereof with a resin coating layer comprising a cured body of a methyl silicone resin containing not less than 70% of T-unit and a methylated melamine resin having molecular weight of not less than 700. This developer is not lowered in flowability, generates no spent particles and presents stable electric charging characteristics. Accordingly, the developer of the present invention is suitably used where there is used a toner containing no electric charge controlling agent.
