ABSTRACT:
An apparatus for constituting a rotary magnetic brush comprises a hollow cylindrical member (11) with permanent magnetic strips arranged axially along its periphery. The strips have outwardly directed magnetic poles in a configuration in which north poles and south poles alternate circumferentially. A tube (13) made of non-magnetic substance surrounds said member without touching it. The tube is intended to have particles of magnetic powder deposited on its surface and the particles are made to rotate by rotating the member (4). This causes a rotating layer or "brush" of magnetic particles to be formed on said tube. Said member (11) and the tube (13) which surrounds it are longer than the "brush": An end portion projects beyond the "brush" and is housed in an electrical stator (14) which drives the member (11) by making use of the poles which form the brush. The invention applies to developing electrostatic latent images.
