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