ール。A permanent magnet roll for electrostatic development that has a magnet structure formed by forming a plurality of magnetic poles at radial positions from the shaft center inside a non-magnetic cylindrical sleeve and is relatively rotatably supported, The magnet structure includes a plurality of permanent magnets, a body made of synthetic resin with a plurality of grooves for inserting and supporting the permanent magnets in the axial direction of the outer circumferential surface, and a body made of synthetic resin, which has a plurality of permanent magnets in the axial direction on both end surfaces of the body. (This refers to a protruding shaft with a metal part that makes contact with the bearing.)
A permanent magnet roll for electrostatic development consisting of an integrated magnet storage body.
