Electrostatic latent image developing toner

Abstract

Abstract PURPOSE:To improve removal and recovery of a toner from the surface of a photoreceptor, by attaching fine powders of carbon black and a metal salt of fatty acid to the surface of an electrostatic latent image developing toner contg. a thermoplastic resin as a main component. CONSTITUTION:A fine powder of a metal salt of fatty acid as well as that of carbon black are attached to the surface of the toner. The attachment of the carbon black makes it possible to attach said metal salt uniformly, and even when it is used as a toner in the developer used for the electrophotographic copying method using a powder image transfer system, the removal and recovery of the toner from the surface of the photoreceptor are carried out favorably without exerting adverse effect, such as deterioration of image quality of copies.
