Abstract
L'appareil selon l'invention comprend, dans un dispositif de développement électrographique 10, une électrode 12 reliée par le conducteur 13 à un circuit de comparaison et de régulation 14 grâce auquel la teneur en toner du révélateur venant en contact avec l'électrode 12 est détectée en vue de l'émission, quand des limites supérieure et inférieure sont atteintes, d'un signal de déclenchement ou d'arrêt de réapprovisionnement en toner du réceptacle 100.
