Abstract
L'invention concerne un dispositif de développement d'images électrostatiques. Elle se rapporte à un dispositif de développement dans lequel un aimant multipolaire 12 et un organe cylindrique creux 9 formé d'une matière non magnétique tournent tous deux dans le même sens à des vitesses différentes, et une couche d'agent de développement dont l'épaisseur est fixée par une lame 11, avance en sens opposé et permet le développement d'une image électrostatique portée par un tambour 1. Application au copieurs électrostatiques.
