Bag-in-Box-Anordnung für Toner

摘要

A powder container (1) for an electrophotographic image forming apparatus includes a deformable bag (2) and a powder discharging portion (3) made up of a tapered portion (7) and a toner outlet (8). A buckling reducing device (20) reduces the buckling of part of the bag (2) adjoining the tapered portion (7) and toner outlet (8). The powder container (1) prevents the discharge of powder from being deteriorated by buckling, thereby reducing the amount of powder to be left in the container (1). Further, a device (30) is provided for maintaining the upright position of the bag (2). A powder discharging device for discharging the powder from the powder container is also disclosed.
