Abstract (en)
[origin: EP0018078A1] An apparatus (20) which develops a latent electrostatic image with magnetic particles (54). The apparatus (20) includes a member (62) having a multiplicity of magnetic fibres (66) extending outwardly therefrom. At least a portion of the fibres (66) have the free end regions thereof contacting the latent image. A magnet field attracts the particles (54) to the member (62). Relative movement between the member (62) and magnet field moves the particles (54) into contact with the latent image and moves the free ends of the fibres (68). As the particles (54) are deposited on the latent image, the end regions of the fibres (66) move forming a substantially uniform particle image.
