Abstract:
A powder container for an image forming apparatus includes: a rotatable powder storage storing powder; an opening on one end of the powder storage, through which a nozzle can be inserted; and a scooping portion to scoop up powder on an opening side, and supply the powder to a powder receiving hole of the nozzle when the powder storage rotates. The scooping portion includes a scooping surface extending inwardly from an inner wall surface of the powder storage and an inner end portion extending in a rotation axis direction of the powder storage, with an edge approximately parallel to the rotation axis. In a cross-section perpendicular to the rotation axis, the scooping surface is inclined toward an upstream side in a rotation direction of the powder storage with respect to a virtual line that passes through the rotation axis and is tangent to the edge of the inner end portion.
