    • To provide a magnet roller having a high magnetic force at low cost even if magnetized in a relatively weak magnetic field, having a magnetic force (800 G or higher) sufficient for development even if a plurality of magnetic poles are provided in a main magnetic pole part, and having good resistance to oxidation. The magnet roller (1) of the present invention includes a body part (3) and a shaft part (2) supporting both ends of (3). A plurality of magnetic poles are provided in a magnetized manner in an outer peripheral face of (3), made up of a rare-earth bond magnet made of rare-earth magnetic powder having a composite phase of a hard magnetic phase and a soft magnetic phase both magnetically exchange-interacting with each other and having a coercive force (iHc) of 5 KOe or lower and a residual magnetic flux density (Br) of 5 KG or higher.
    • 即使在相对较弱的磁场中磁化的情况下,即使在主磁极中设置多个磁极,也具有足以显影的磁力(800G或更高)的磁力,以低成本提供具有高磁力的磁性辊 部分,并且具有良好的抗氧化性。 本发明的磁性辊(1)包括主体部(3)和支撑(3)的两端的轴部(2)。 在由(3)的外周面以磁化方式设置多个磁极,由具有硬磁相和软磁的复合相的稀土类磁粉制成的稀土类磁铁 相位彼此磁交换相互作用并具有5KOe或更低的矫顽力(iHc)和5KG或更高的剩余磁通密度(Br)。
