DEVELOPER CARRYING BODY AND ITS PRODUCTION

PURPOSE:To obtain a line image having substantial density even if a one-component toner is used by providing a composite layer of rubber and magnetic material on a conductive base and magnetizing the composite layer then forming an electrode layer embedded with many conductive particles into a dielectric adhesive agent on the surface of the rubber layer. CONSTITUTION:A composite layer 5' consisting of rubber and magnetic material powder is formed on, for example, a circular cylindrical conductive base 4 and thereafter the composite layer is magnetized to form a rubber magnet layer having a thickness t5'. The surface is then ground to form a smoothed layer 5. A dielectric adhesive agent layer 6b is thinly formed on the layer 5 and after conductive particles 6a are adhered to the layer 5, the adhesive agent 6b is dried. The particles 6a are coated with the same or different adhesive agent 6b' and thereafter the adhesive agents 6b, 6b' are cured. The surface is ground to expose the surface area of the particles 6a to >=45% of the entire surface area of the electrode layer 6 and is finished smooth to such a thickness t6 at which dislodging of the particles 6a is prevented. The developer carrying body to provide the one-component toner image with which the substantial density of even the line image is obtainable is thus obtd.
