Abstract
PURPOSE: To obtain a magnet with magnetic poles in peripherical surface by applying magnetic field to arrange radially ferromagnetic axes around magnetic pole, when isotropic sintered ferrites are formed around the periphery of shaft and charged.
CONSTITUTION: An isotropic sintered ferrite 2 is wound around shaft 1 in roll-shape and is charged, and a roll-shaped magnet used to electrophotographic duplicator, etc. is made. Metal molds is used consisting of the magnetic material lower mold 10 that sector-like concave parts 11 are provided successively, magnetic material upper mold 12 that nearly wedge-shaped non-magnetic materials 13 are provided with under portion at regular intervals and sector peripherical surface is formed, and side molds 14, 15 that face each other across 10, 12. Coils 16, 17 are wound up the sides of upper mold 10 and under mold 12 respectively. In this constitution, when outer peripherical parts o of sector-like space are added up, they make outer periphery of magnet 2 and when inner peripherical parts q of sector-like space are added up, they make inner periphery of magnet 2. Magnetic force of periphery of magnet 2 is strengthened by charging used these kinds of metal molds.
