Powder accommodating device and image forming apparatus

A powder accommodating device, comprising:

• an accommodating portion that has an opening at one end, is installed horizontally to accommodate powder, and transports the powder toward the opening by rotation;
• a lid portion that has a cylindrical inner wall surface, is provided with an outlet port open downward for the powder, includes a hollow portion that is open facing the opening, covers the opening and is held in a non-rotational state;
• and
• an agitation portion including:
• a cylindrical portion that is disposed in the lid portion, communicates with the opening, and rotates integrally with the accommodating portion when receiving a driving force;
• and a plurality of agitation rods that each have a rod shape protruding from the cylindrical portion in a rotation axis direction in a direction away from the accommodating portion and the cylindrical portion and circulate along the inner wall surface to agitate the powder in the hollow portion, wherein
• the agitation portion further comprises a driving force receiving portion that receives a rotational driving force and protrudes from the cylindrical portion in the same direction as the agitation rods at a position of a rotation center of the cylindrical portion,
• a first pair of agitation rods among the plurality of agitation rods are connected to each other via a first beam provided at a position out of the cylindrical portion with the driving force receiving portion interposed in the middle of the first beam,
• a leading end of each of the first pair of agitation rods is directly connected to the driving force receiving portion, and another portion of each of the first pair of agitation rods is directly connected to the cylindrical portion, and
• the first beam is the only direct connection between the first pair of agitation rods and the driving force receiving portion.
