Abstract
A toner cartridge, the cartridge having a first and second section. A toner material is located in the first section and maintained in the first section by a gasket. The gasket comprises a flexible substrate having attached to one surface thereof, a sealing material. The gasket is inserted between the first and second sections such that the substrate is in contact with the first section and the sealing material is preferably in contact with the second section. When the gasket is removed from the toner cartridge, toner material present in the first section is allowed to pass into the second section and into operable contact with a toner carrying apparatus operably connected to the second section of the toner cartridge.
