Filed: 1990-06-04
Abstract: PURPOSE:To secure the sufficient quantity of toner adhesion and that of toner electrostatic charge and to make it possible to carry much sufficiently charged non-magnetic toner stably for a long period by forming the surface of a developer carrier as an almost smoothed surface and mixing high dielectric parts respectively having specified dielectric constants at the rate of fine area. CONSTITUTION:A developer carrier 20 completing development is rotated in an arrow direction and comes into contact with a toner feeding member 40. Residual toner in a non-image part which has not been developed is mechanically and electrically scraped and low dielectric parts are frictionally charged with electricity. In this case, the charge of the image carrier 20 and that of toner due to the preceding development are frictionally uniformed and initialized. Toner carried by the member 40 is frictionally charged and electrostatically stuck to the carrier 20. Having an electrostatically difference due to the high and low dielectric parts, the carrier 20 generates an electric field inclination. This carrier 20 is produced by forming a high dielectric layer having >=5 dielectric constant on a conductive supporting body, forming grating-like grooves on the layer, embedding a dielectric substance having <=3 dielectric constant in the grooves, and smoothing the formed surface.
