Abstract
A toner cartridge in which a container defines an open ended chamber. The container is adapted to store a supply of toner in the chamber thereof. The open end of the chamber is sealed. A passageway is formed through the toner in the chamber. As the seal is peeled from the open end of the chamber, toner is discharged therefrom. As toner is discharged from the chamber, air displaced from the hopper receiving the toner moves from the hopper through the passageway onto the upper surface of the toner. In this way, displaced air does not impede the flow of toner particles and maintains a substantially uniform pressure on the discharging toner particles.
