<P>PROBLEM TO BE SOLVED: To obtain a highly precise image by reducing vibration of a developing device having a rotational magnetic roller, which is caused by magnetic interference of the magnetic roller. <P>SOLUTION: An additional magnetic pole is disposed for eliminating variations in rotation torque, which result from magnetic interference caused by the rotational magnetic roller and another magnetic pole. Thus, vibration of the developing device is reduced. <P>COPYRIGHT: (C)2003,JPO |
