ELECTROPHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce magnetic interference between magnet rolls due to the rotation of the magnet roll and to obtain a high-definition printed image in an electrophotographic device having a plurality of developing rolls equipped with a sleeve and the magnet roll. SOLUTION: The vibration of a developing device for the electrophotographic device is reduced by setting the angle of a magnetic pole and a distance between the adjacent magnet rolls out of a plurality of developing rolls used in the developing device for the electrophotographic device and equipped with the sleeve and the magnet roll so that magnetic interference may not be emphasized on the magnetic pole of the rotating magnet roll and that of the non-rotating magnet roll.
