るトナーカートリツジ。[Scope of Claim for Utility Model Registration] A toner cartridge that stores toner inside and opens the toner discharge opening by peeling off a sealing member that closes the toner discharge opening and discharges the toner stored therein: The cartridge is divided into a toner storage chamber that stores toner and a pressure regulation chamber that communicates with the outside air, and a stretchable pressure regulation membrane with a high elastic modulus is provided at the interface between the toner storage chamber and the pressure regulation chamber. The pressure regulating membrane expands and contracts as the volume of air inside the toner storage chamber of the toner cartridge changes, thereby regulating the pressure inside the toner storage chamber so that it is always equal to the outside pressure. This toner cartridge is characterized by:
