Abstract
A disposable toner cartridge includes a cartridge container having a bottom opening for discharging toner and a sealing film that may be peeled off of the bottom opening in a first direction. A covering member is attached to the cartridge container beneath the sealing film and engages the sealing film such that movement of the covering member in a first direction seals the sealing film from the bottom opening and in a second direction reseals the bottom opening with the sealing film.
