Abstract

Eine Kassette für Kopiergeräte und dergleichen, die eine Bild­ trommel (4) und einen Tonervorratsbehälter (2) enthält, in dessen Wand eine verschließbare Tonereinfüllöffnung (11) vorgesehen ist, weist wenigstens ein entfernbares Sperrelement (13) auf, das den Transportweg einer Alttoner-Rückführungs­ einrichtung (7, 8, 9) unterbricht und dadurch den Austritt von Toner aus der Kassette verhindert und/oder die Auslaß­ öffnung einer Entwicklervorratskammer verschließt und im Be­ reich der Auslaßöffnung des Tonervorratsbehälters mit einer Durchlaßöffnung versehen ist, durch die hindurch der Toner in einen Vorratsraum gelangt, aus dem der Toner nur mit Hilfe einer Tonertransportvorrichtung (116) austreten kann.
