ロール。A permanent magnet for electrostatic images that has a magnet structure formed by forming a plurality of magnetic poles at radial positions from the center of the shaft inside a non-magnetic cylindrical sleeve and is relatively rotatably supported. In the roll, the magnet structure includes a plurality of rod-shaped permanent magnets, a shaft core material having radial fins in at least two directions, and a plurality of grooves on the outer circumferential surface for fitting and supporting the rod-shaped permanent magnets in the longitudinal force direction. a pair of shaft stop members each having a fixing part that fits into or clamps both ends of the shaft core material, and a rotary shaft erected on each outer end surface; A permanent magnet roll for electrostatic development, comprising a thermoplastic resin tube that encloses the entire rod-shaped permanent magnet along its outer periphery.
