気ブラシ現像装置。A developing roll comprising a rotatable non-magnetic sleeve and a permanent magnet having a plurality of magnetic poles on its surface fixedly disposed within the sleeve is placed opposite to a carrier having an electrostatic latent image on its surface. A plurality of magnetic poles are installed, and among the magnetic poles, developing magnetic poles facing the carrier are arranged so that different polarities are alternately arranged, and on both sides of the developing magnetic poles, there are transport magnetic poles of opposite polarity,
In a magnetic brush developing device, the developing rolls mainly form magnetic brushes while passing the developing image between adjacent developing rolls, and the magnetic brushes rub the surface of the carrier. A magnetic brush developing device characterized in that a single developer flow is formed between adjacent developing rolls by bringing opposing transport magnetic poles close to respective developing magnetic poles.
