構成したことを特徴とする磁気ブラシ現像装置。A non-magnetic sleeve rotatably provided opposite to a carrier having an electrostatic latent image on its surface, and a permanent magnet having a plurality of magnetic poles on its surface fixedly disposed within the sleeve. A plurality of developing rolls are installed, and among the magnetic poles, the developing magnetic poles facing the carrier are arranged so that the developing magnetic poles are alternately lined up with different polarities, and In a magnetic brush developing device that has a conveying magnetic pole and forms a magnetic brush on the developing roll while receiving and passing the developer between adjacent developing rolls, the developing magnetic pole of the second developing roll is connected to the developing magnetic pole of the first developing roll. Formed longer than the magnetic pole,
A magnetic brush developing device characterized in that the magnetic force at both ends of a developing magnetic pole is greater than the magnetic force at the center.
