ABSTRACT:
A magnetic brush developing apparatus for an electrophotographic copying machine or electrostatic recording machine has a sleeve in which a plurality of magnetic pieces are arranged in alternating polarity. Each piece has a shape which produces two or more magnetic peaks. The sleeve and the magnets are rotated in opposite directions. As a result of the the above, a soft developer body is obtained, and density unevenness or striping of the image is avoided.
