    摘要： 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.

    摘要： A driving force transmission mechanism includes a connection for integrally rotating a driving shaft on the driving source side and a driven shaft of a rotary member. The connection includes a tubular boss portion; and a fitting shaft portion fitted into the tubular boss portion. An inner shaft portion is provided in a projecting manner from bottom center of the tubular boss portion toward inside the tubular boss portion. An inner recessed portion into which the inner shaft portion fits is provided in center of a leading edge plane for fitting of the fitting shaft portion. Micro gaps are provided between an inner surface of the tubular boss portion and an outer surface of the fitting shaft portion and between an inner surface of the inner recessed portion and an outer surface of the inner shaft portion.
