摘要： PROBLEM TO BE SOLVED: To solve a problem that a method of increasing the molecular weight of a resin binder mixed with ferromagnetic powder is employed conventionally so as to improve the traverse rupture strength of a magnet roller incorporated in a copying machine etc., and since this method improves the traverse rupture strength, however lowers magnetic characteristics, balance between the traverse rupture strength and magnetic characteristics is maintained by expensively controlling the water amount in the whole resin magnet composition.
SOLUTION: The resin magnet composition improves the traverse rupture strength without sacrificing the magnetic characteristics and moldability by adjusting the water amount in the ferromagnetic powder before being mixed with the resin binder to 0.01 to 0.06 wt.%.

摘要： PROBLEM TO BE SOLVED: To solve the problem that filling with a molten resin magnetic material having a cavity fill amount exceeding 98 wt.% under a primary pressure (injection pressure) in a conventional molding method may cause a lot of voids to occur in the inside of the molded article, consequently to increase a variation or ripple in axial magnetic flux density, and deteriorate the strength of a body part with creases occasionally occurring during transport or during use.
SOLUTION: The ratio of a fill amount due to the primary pressure (injection pressure) and pressure keeping when an outside diameter of a magnet roller body part is less than ϕ12 mm is set to be (a primary pressure):(a hold pressure)=85-98 wt.%:15-2 wt.%, and the ratio of the fill amount due to the primary pressure and the pressure keeping when the outside diameter of the magnet roller body part is ϕ12 mm to ϕ18 mm is set to be (the primary pressure):(the hold pressure)=92-98 wt.%:8-2 wt.%. The axial magnetic flux density becomes uniform and the strength of the body part are improved by molding a shaft part integrated magnet roller.
