Abstract: In a magnet roller of the magnet piece bonding type, the main pole has a high magnetic flux density and the other pole has an asymmetric magnetic flux density pattern with respect to the magnetic flux density peak position. The magnet piece of the main pole is formed by injection molding while performing pole-anisotropic orientation of magnetic particles of the magnet piece. The magnet piece of the other pole is formed by extrusion molding while orientating the magnetic particles in a certain direction inclined by 5 degrees of more with respect to the center line of the radial direction of the magnet piece. The magnet roller is formed by combining the magnet piece of the main pole and the magnet piece of the other pole.
