像する装置において、現像スリーブ内に設けられたマグ
ネットの少くとも潜像担持体に対面する位置のマグネッ
トの長手方向両端部近傍に、分離溝あるいは磁石のない
部分を設けて、その位置に反発磁界を形成せしめるよう
にしてなる磁気ブラシ現像装置。In an apparatus that develops a latent image carrier with a developer held on a developing sleeve, separation grooves are provided in the vicinity of at least both longitudinal ends of the magnet provided in the developing sleeve at a position facing the latent image carrier. Alternatively, there is a magnetic brush developing device in which a part without a magnet is provided and a repulsive magnetic field is formed at that position.
