PROBLEM TO BE SOLVED: To provide a compsn. for a resin magnet which makes it possible to obtain good magnetic force characteristics by suppressing the degradation in magnetic force by the disturbance in the flow of the resin at the time of extrusion without the complication of the structure of an extrusion molding machine and to surely obtain molding having sufficient mechanical strength when obtaining the resin magnet molding, such as magnet roller, by an extrusion molding method. SOLUTION: The resin binder of the compsn. for the resin magnet prepd. by dispersing and mixing magnetic powder with this resin binder contains a vinyl chloride resin or its copolymer and an ethylene-vinyl acetate copolymer resin. The vinyl acetate content of this ethylene-vinyl acetate copolymer resin is >=25 to <60 wt.%. |
