Abstract

Appareil d'application de particules d'agent de virage sur une image magnetique. L'appareil comprend un rouleau magnétique tournant, une lame disposée entre celui-ci et la surface qui porte l'image latente, la lame présentant une face de coin conçue pour créer une onde stationnaire fluidisée de particules qui entre en contact avec la surface portant l'image latente lorsque le tambour tourne. Application aux appareils de reproduction par image latente magnétique.
