。A plurality of developing rolls each having a rotatably provided non-magnetic sleeve and a permanent magnet body having a plurality of magnetic poles on the surface are installed facing a carrier having an electrostatic latent image i on its surface,
Among the magnetic poles, developing magnetic poles facing the carrier are arranged so that different polarities are arranged alternately, and conveying magnetic poles of opposite polarity are provided on both sides of the developing magnetic poles, and continuous development is carried out along each of the developing rolls. A magnetic brush developing device in which a flow of agent is formed is characterized in that mutually opposing transport magnetic poles of adjacent developing rolls are arranged so that different polarities face each other, and a guide member is disposed between the magnetic poles. Magnetic brush developing device.
