Zusammenfassung:A magnet roller (133) includes a magnetic field generator being columnar, a support element being columnar (33, 34), coaxially provided at both ends of the magnetic field generator (31), and whose diameter is smaller than that of the magnetic field generator (31), a level element extending along an axis of the magnetic field generator (31) with a distance from the axis, the distance larger than the diameter of the support element (33, 34), and a high magnetic power element being a main magnetic pole provided on the level element, extending long along the axis of the magnetic field generator (31).
