Abstract

L'invention concerne une cartouche de toner (200) montée de façon détachable sur un dispositif de formation d'image (180), comprenant un boîtier qui est doté à l'intérieur d'une chambre à toner permettant de stocker du toner (204), une entrée de toner (188) et une sortie de toner (252) étant alignées et mises en correspondance entre elles, et un élément commutateur (250) étant situé entre la sortie de toner (252) et l'entrée de toner (188) afin de commander la commutation de la sortie de toner (252) et de l'entrée de toner (188) entre une position fermée et une position ouverte. Une partie de montage d'élément de commutation (270) est située sur une surface extérieure du boîtier dans une position opposée à la sortie de toner (252), l'élément de commutation (250) comprend un corps principal qui est doté en son centre d'une ouverture centrale, le corps principal coulisse sur un plan de la partie de montage d'élément de commutation (270), et dans une direction de montage de cartouche de toner (200), l'élément de commutation (250) est maintenu stationnaire avec l'entrée de toner (188) précédant la sortie de toner (252), puis la sortie de toner (252) est mise progressivement en communication avec l'entrée de toner (188), de façon à résoudre le problème selon lequel la contamination se produit à une position qui ne correspond pas à une sortie de toner (252) dans un dispositif de formation d'image lorsqu'un élément de commutation d'une cartouche de toner existante est tourné.
