Tonerbehälter mit Halterung für Abdichtfolie

摘要

In a toner cartridge (25) for supplying toner to the developing unit in a xerographic image forming apparatus, the casing containing toner has two toner discharge openings sealed prior to installation by a sealing film (28,29) having a sealing portion (30) peel-separably affixed to the casing around the toner discharge openings, as well as a peel-separating leader portion (32). The sealing film overlaps itself, having open opposite lateral edges. The toner cartridge is fitted with retaining elements affixed to the casing along opposite lateral edges of the toner discharge openings, for covering the open opposite lateral edges of the sealing film. An installation seat having a toner-disgorging opening corresponding to the toner discharge openings is fixed to the end of the toner cartridge casing. The installation seat (40) includes pressing elements therein disposed over the retaining elements for maintaining external pressure on the retaining elements.
