发明名称 POWDER CONTAINER AND IMAGE FORMING APPARATUS
摘要 A powder container used in an image forming apparatus. The powder container includes a rotatable powder storage that stores therein the powder for image formation, the rotatable powder storage to rotate about a rotation axis; an opening on one end of the powder storage, through which a nozzle of the image forming apparatus is to be inserted; and a scooping portion to scoop up powder on an opening side, and to supply the powder to a powder receiving hole of the nozzle when the powder storage rotates. The scooping portion includes a scooping surface that extends inwardly from an inner wall surface of the powder storage. The inner end portion of the scooping surface extends in a rotation axis direction of the powder storage. The edge of the inner end portion is 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.
