Abstract
PURPOSE:To nearly eliminate the magnetic flux density on the surface of a sleeve between the same adjacent poles of a magnet roller, by providing an exciting yoke of a comparatively small opposite magnetic pole between exciting yokes for forming the same adjacent poles of the magnet roller, and forming a magnetic field of a molten resin. CONSTITUTION:By providing an exciting yoke 6' of a comparatively small opposite magnetic pole between exciting yokes 6 for forming the same adjacent poles of a magnet roller, a magnetic field of a molten resin is formed in a cavity of a metallic mold 8. As a result, magnetic power contained in the molten resin is magnetized, and also, its axis of easy magnetization is oriented in accordance with a position and strength of the exciting yokes 6, 6'. Consequently, a magnetic pole is generated on the surface of the roller, and a magnetic flux line 9 for connecting this magnetic pole is formed in the roller. In the resin magnet which is oriented in such a way, an N' pole is weaker than both adjacent S1 and S2 poles, therefore, on the surface of a sleeve separated a little from the surface of the roller, the magnetic flux density of the N' pole is nearly eliminated.
