A tire including: a circular tire frame formed from a resin material; and a metal reinforcing cord member wound on an outer circumference of the tire frame, at least a portion of the metal reinforcing cord member being covered by a covering mixture including at least a thermoplastic resin and a specific elastomer selected from the group consisting of (1) to (3) below: (1) a thermoplastic polyurethane-based elastomer; (2) a thermoplastic polystyrene-based elastomer; and (3) a thermoplastic olefin-based elastomer including at least one selected from the group consisting of an acid-modified thermoplastic olefin-based elastomer having an elastic modulus of less than 140 MPa and a non-acid-modified thermoplastic olefin-based elastomer having an elastic modulus of less than 140 MPa.
摘要:
The substrate for photosensitive drum of the invention for use in electrophotographic process is produced by ultrasonic-welding a resin-made flange or gear flange to an end portion of a cylindrical substrate made from an electroconductive resin composition prepared by dispersedly mixing an electroconductive material and a filler into a polymer matrix. The ultrasonic welding permits an efficient production of the substrate for photosensitive drum and ensures a high rotation accuracy of the substrate for photosensitive drum. With such a substrate for photosensitive drum, images with high quality can be formed.

Provided is an electroconductive endless belt in which a decrease with use in the gloss value caused by frictions and the like with papers and cleaning blade is suppressed. The present invention is an electroconductive endless belt used in an image forming apparatus. In the electroconductive endless belt, the base resin of the electroconductive endless belt comprises a polyalkylene terephthalate resin in combination with a naphthalene ring-containing thermoplastic resin and/or a naphthalene ring-containing thermoplastic elastomer having a melting point higher than that of the polyalkylene terephthalate resin, and the mass ratio of the polyalkylene terephthalate resin to the naphthalene ring-containing thermoplastic resin and/or the naphthalene ring-containing thermoplastic elastomer in the base resin is in the range of 90/10 to 50/50.
