ELECTROPHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a high-quality printed image free from jitter by preventing the vibration of a developing machine caused by magnetic field interference between magnet rolls in an electrophotographic device equipped with a plurality of developing rolls consisting of a plurality of sleeves and a plurality of developing rolls. SOLUTION: By inserting a magnetic shielding plate between a core rotating type developing roll where the sleeve and the magnet roll are rotated and another developing roll adjacent to the developing roll, magnetic field formed by both magnetic rolls is intercepted so as not to interfere with each other, whereby the magnetic field interference between the developing rolls is prevented.
