いという問題があった。However, in conventional resin compositions, there are limits to improving the filling rate of magnetic materials such as ferrite powder due to processability and productivity. Therefore, efforts have been made to externally apply a magnetic field or mechanical force necessary to orient the ferrite powder in order to improve the magnetic properties from the processed surface. However, there were limits to its magnetic properties. That is, due to the resin, there is a problem that the filling rate of the magnetic material per unit volume is lower than that of ferrite sintered crystals or the like.

．． It was molded using an extruder with a diameter of φθ5. In the first step, the core material is coated with a resin magnet composition, and in the second and subsequent steps, a die with a high temperature and compression zone for extracting polymer compounds with a molecular weight of 10,000 or less is attached and extrusion molding is performed. A roll body was obtained in which a resin magnet composition containing highly filled ferrite powder was formed around a core material with a thickness of .5 mm. This roll body was processed to a predetermined size and magnetized with six poles to obtain a Lumagnetino roll having the magnetic properties shown in Table 1.
