<P>PROBLEM TO BE SOLVED: To easily change a magnetic force pattern formed around a magnet roller divided into two. <P>SOLUTION: A cylindrical roller main body 9 is constituted by combining semi-cylindrical members 50 and 60. Either groove-shaped or hole-shaped attaching parts A to G are formed in the longitudinal direction (direction of a roller shaft C<SB>0</SB>) of the roller main body 9, and a corresponding magnetic force adjusting member is attached to the formed attaching part. The roller main body 9 is formed of a resin magnet and the magnetic force adjusting member is formed of a magnet body. By adjusting the position of the attaching part and the strength of the magnetic force of the magnetic force adjusting member, the magnetic force pattern formed around the roller main body 9 is properly changed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
