Abstract
A method of manufacturing a tube-covered roller for fixing includes a step of setting a core material in a substantially central portion of a cylindrical mold and setting, outside the core material, a tube and a resin layer which is capable of coming into contact with an inner surface of the mold, a step of putting a rubber material between the core material and the tube and hardening the rubber material to produce a roller, and a step of, after detaching the roller covered with the tube and the resin layer from the mold, removing the resin layer from the roller.
Claims22
A method of manufacturing a tube-covered roller for image fixing, comprising the steps of:
- setting a core material in a substantially central portion of a cylindrical mold and setting, outside said core material, a first tube and a resin layer which is capable of coming into contact with an inner surface of said mold;
- putting a rubber material between said core material and said first tube and hardening said rubber material to produce a roller;
- and
- after detaching said roller covered with said tube and said resin layer from said mold, removing said resin layer from said roller.
A method of manufacturing a tube-covered roller for image fixing, comprising the steps of:
- placing a resin layer on a first tube;
- covering a roller having a rubber layer with said first tube having said resin layer placed thereon;
- and
- removing said resin layer from said roller covered with said first tube.
A method of manufacturing a tube-covered roller for image fixing, comprising the steps of:
- setting a core material in a substantially central portion of a cylindrical mold, setting a tube outside said core material and setting a cylindrical resin member outside said tube in such a way as to come into contact with an inner surface of said mold;
- putting a rubber material between said core material and said tube and hardening said rubber material to produce a roller;
- and
- detaching said roller covered with said tube from said resin member left at said mold.
