ABSTRACT:
Disclosed is a toner cartridge in which not only a first zone is provided for containing a toner therein but also a second zone is formed and a first opening and a second opening are formed adjacent to each other in these zones, respectively, one end of a sealing member being located on the edge, on the side of the second opening, of the first opening while the other end of the sealing member is secured to the confronting edge of the second opening, and the sealing member is peeled in the state where the sealing member is stuffed into the second zone through the second opening. In this toner cartridge, the attachment size of the cartridge is shortened and the attachment operation and the operation of peeling the sealing member are simplified. Furthermore, the carriage which finishes replenishment of the toner is drawn out from the toner supply zone of the developing device by a one-touch operation without touching the sealing member by hands, and even if the toner adheres to the sealing member, an advantage is attained, in that hands of an operator and surroundings are not contaminated with the toner.
