Developing apparatus
 A developing apparatus is arranged to supply toner onto the surface of a developing sleeve to form on it, a thin layer of toner triboelectrically charged by a restricting member, and to feed the toner layer onto an electrostatic latent image holding member having an electrostatic latent image formed on it for developing the latent image. At least part or all of the surface layer of the developing sleeve is formed by a mixed material mainly composed of crystalline polyamide resin and non-crystalline polyamide resin.
