    摘要： A developer for developing an electrostatic latent image, said developer comprising (i) a toner containing at least a binder resin and a colorant, and (ii) substantially spherical silica fine particles having a bulk density of not less than 300 g/l; a process for producing the developer; and a process for forming a toner image using the developer. The developer exhibits satisfactory fluidity and satisfactory cleanability while retaining environmental stability and durability. The developer causes no toner filming on the surface of a photoreceptor, the surface of a carrier, or the surface of a charge-imparting member.

    摘要： An electrophotographic dry toner comprising a binder resin and a colorant, having externally added thereto an inorganic compound, preferably spherical silica particles, having been surface treated with at least one treating agent selected from the group consisting of a treating agent selected from a polyethylene, a fatty acid metal salt, and a solid alcohol containing from 20 to 60 carbon atoms. The toner is prepared by treating the inorganic compound with a dispersion or a solution of the treating agent in a solvent and adding the thus surface-treated inorganic compound to a toner. The toner exhibits satisfactory fluidity, satisfactory cleanability, excellent environmental stability, and excellent durability and causes no toner filming phenomenon on a photoreceptor, a carrier used in a two-component developer system, or a charging part used in a one-component developer system.

    摘要： A positively chargeable electrophotographic toner is disclosed, which is prepared by adding to toner particles silica fine particles having been surface treated with a homo-or copolymer comprising, as a monomer component, a dialkylaminoalkyl acrylate or a dialkylaminoalkyl methacrylate in the form of a quaternary ammonium salt. The toner has improved fluidity and improved anti-caking properties while exhibiting satisfactory charging properties and environmental stability and causing no image defects.
