An image drum, of electrically conductive resin, includes a cylinder element adhesively bonded, using a non-solvent adhesive, to a bearing/drive element. To insure secure attachment of the bearing/drive element to the cylinder element, the adhesively bonded surface of the cylinder resin element is activated, by ultraviolet light in the wavelength range of 180 to 255 nm or by corona discharge, prior to bonding. The volume resistivity of the cylinder element 1 is 10 4 Ω-cm. The most suitable resins that can be used for cylinder element 1 include thermoplastic resins including polyethylene, polypropylene, polystyrene, and polyphenylene sulfide, and thermosetting resins including phenol, melamine, epoxy, and unsaturated polyester. Both groups should be made conductive in the range of 10 4 Ω-cm, or less, resistivity. The required conductivity can achieved by adding carbon black to the chosen material of which cylinder element 1 is made. |
