Abstract
L'invention concerne les appreils de développement d'images électrostatiques. Elle se rapporte à un appareil dans lequel une lame 16 de raclage limite l'épaisseur de la couche d'agent de virage formée sur un manchon 14, dans un champ magnétique créé par un aimant 15, l'épaisseur de la couche d'agent de virage étant très régulière et permettant le développement d'images très uniformes et d'excellente qualité, sans voile. Application au développement des images électrostatiques latentes.
