摘要： PROBLEM TO BE SOLVED: To provide a magnet roller capable of extending service lives of a photoreceptor and developer and obtaining stable high image quality for a long time by broadening the vicinity of the peak of the flux density of the flux density pattern of a magnetic pole opposed to a developer regulating plate, facilitating the positioning of the developer regulating plate (making a margin large), reducing a gap between the developer regulating plate and a sleeve and thinning the layer thickness of the developer after passing through the developer regulating plate, thereby performing jumping development. SOLUTION: In the magnetic roller formed by sticking plural magnet pieces, either or both of adjacent magnetic poles for regulating developer are provided with a notch formed on the outer peripheral surface of a bonding surface between the magnetic pole for regulating developer and its adjacent magnetic pole.

摘要： PROBLEM TO BE SOLVED: To solve a problem of not being able to cope with the higher speed and higher image quality of a recent full-color machine since high magnetic flux density cannot be secured inexpensively in a conventional cylindrical magnet roller due to the securing of the high magnetic flux density by using an expensive rare earth based magnet block and the imbedding of the same in a groove in the axial direction of the cylindrical magnet. SOLUTION: The cylindrical magnet which is formed by molding a mixture mainly composed of ferromagnetic powder and a resin binder has the cylindrical magnet imbedded with a plurality of numbers of magnet pieces that are repulsed magnetically from each other in an indention in an outer periphery section.

摘要： PROBLEM TO BE SOLVED: To solve the problems that conventional magnet rollers react to applied magnetic fields and deform due to the use of a ferromagnetic body powder during molding magnet pieces, thereby causing crack, etc., it is difficult to carry out continuous extrusion molding by rupture of molded articles, it is difficult to carry out lamination with sufficient accuracy by generation of meandering when laminating magnet pieces on a shaft periphery surface, which may result in image degradation, and in particular, when a ferromagnetic powder is used on the basis of a rare earth-based magnetic powder, conventional magnet rollers are very easy to react to applied magnetic fields and it is more difficult to carry out continuous extrusion molding, due to the high residual magnetic flux density, and so on. SOLUTION: A magnet material composition for extrusion molding is used wherein, in a mixture based on a ferromagnetic powder and resin binder, the weight ratio of a ferromagnetic powder in the mixture is 50-95 wt.%, the melt viscosity of the mixture is 30-45 N×m, and the bending strength after molding is 150×10 5 -250×10 5 N/m 2 .

摘要： PROBLEM TO BE SOLVED: To solve the problem that a conventional magnet roll, which is integrally molded with a resin magnet composition, is low in axial strength and easily causes a warp, and the conventional magnet roll, in which a metal shaft is inserted, degrades its own magnetic force and causes curvatures and cracks.
SOLUTION: On both end surfaces or one end surface of a magnet roll, a convex part and/or a concave part are formed. In this case, the magnet roll is engaged with shaft members whose diameters are equal to the outer diameter of the magnet roll or smaller and which have, on their one ends, collars which are nearly perpendicular to the center of the shaft.
