A resin roller () is produced by disposing a core body () in a forming metal mold () having a cylindrical metal mold () and core supporting members () furnished at both edge parts of the cylindrical metal mold () as well as causing the core supporting members () to hold said both edge parts, and pouring a forming resin into the metal mold and solidifying it. The resin roller () has the core body () of the same outer diameter over a full length and a cylindrical resin-formed body (), sealing members () are furnished around the core body () in the vicinity of both edge parts of the resin-formed body (), and the core body () is disposed such that the sealing members () contact edge faces () at sides of a roller forming space of the core supporting members ().

Device for making a resin roller

A multi-layered endless belt having an arbitrary layer thickness by the thickness of the film and the winding number, a medium conveying belt using the same, and a method and apparatus by which these can be stably produced without various residues in the production process and can be produced with a high general-purpose properties and at a low cost. There are provided a multi-layered endless belt made by winding and heat-welding a polymer material film and a production method thereof, and further a production method of medium conveying belts of various forms fundamentally having a construction in which an electrode pattern and a protective film are laminated thereon, and a novel production method and molding apparatus for molding the multi-layered endless belt by heat-pressing a wound tubular body.
