METHOD FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE

PURPOSE:To provide a satisfactory image which is stable with lapse of time by bringing the surface of an image forming member on which an electrostatic latent image is formed into contact with a specific developer to form a toner image on the member surface and transferring the toner image to a transfer material. CONSTITUTION:The electrostatic latent image is formed on the surface of the image forming member and the surface of such member is brought into contact with the developer contg. at least the toner particles contg. 0.05-20wt% a lubricating agent per weight of the toner in the toner and cerium oxide as the particles independent from the toner particles to form the toner image on the surface of the image forming member. The formed toner image is transferred to the transfer material and the developer remaining on the surface of the image forming member after the transfer is cleaned by a cleaning blade. The lubricating agent is exemplified by graphite, mica, talc, zinc white, PP, polytetrafluoroethylene, etc.
