Title
(EN) METHOD AND DEVICE TO REGULATE TONER IN AN IMAGE FORMING DEVICE
(FR) PROCEDE ET REGULATION DU TONER DANS UN DISPOSITIF DE FORMATION D'IMAGE
Abstract
(EN)
A device to regulate toner within an image forming apparatus. The regulating member has a first section and a toner regulating edge with at least one gap. The regulating member controls the amount of toner that is distributed on the surface of the toner developer roller by contacting the toner developing roller in a contact region. The gap, having at least one upper edge, may regulate toner on the toner developer roller near the contact region. The toner regulating device may prevent inadvertent toner marks that may appear on printed media.
(FR)
L'invention concerne un dispositif de régulation du toner dans un appareil de formation d'image. L'élément de régulation possède une première partie et un bord de régulation du toner comportant au moins un espace. L'élément de régulation commande la quantité de toner distribuée sur la surface du rouleau à révélateur à toner par mise en contact dudit rouleau avec une zone de contact. L'espace, qui possède au moins un bord supérieur, peut réguler le toner sur le rouleau à révélateur à toner à proximité de la zone de contact. Le dispositif de régulation de toner peut prévenir l'apparition de marques de toner indésirables sur le support imprimé.
