Abstract: PURPOSE: To reduce dispersion in dimensions and magnetic intensity characteristics and restrict the occurrence of draw or air bubbles by providing a pipe inside the main body portion of a magnet. CONSTITUTION: A magnet roller 1 has a hollow portion 3 continuous in axial direction inside said magnet roller. The cross section of the hollow portion 3 possessed by the main body portion of magnet can be circular or noncircular. Material of a pipe 5 is not specially restricted, but magnetic materials such as iron or copper are more desired since the magnetic powder of the main body of the magnet roller 1 can be orientatated. Also for its shape, about 10 to 50mm of outer diameter and about 1 to 5mm of thickness are desired. When forming a magnet roller having a more complicated magnetic intensity pattern, a noncircular type can be used. By doing this, the cooling time can be shortened and the dispersion in dimensions and magnetic intensity characteristics can be made extremely small.
