To make a feed roller be by no means inferior to a rubber roller for practical use by integrally sticking or fusing a cylindrical rubber quality part made of a thermoplastic polyester elastomer to a shaft roller construction of a resin made hollow structure.
A thermoplastic polyester elastomer made cylindrical rubber quality part 2, which is a block polymer having a hard segment composed of a polytetra methylene terephthalic acid ester alternately connected to a soft segment composed of a polymethylene glycol, is integrally stuck or fused into a hollow shaft roller construction 1 made of such thermoplastic resins as a polystyrene resin or an ABS resin or a polycarbonate resin. Thus a feed roller compared favorably with a rubber roller in practical use can be manufactured through a simple production process.
