摘要： A developer accommodating unit for accommodating a developer includes a flexible container, provided with an opening for permitting discharge of the developer, for accommodating the developer, and a frame. The flexible container is provided with a fastening hole for fastening said flexible container in said frame. The frame includes a fixing shaft portion fixed in the fastening hole by being inserted into the fastening hole, and includes a retaining portion for preventing the fixing shaft portion from being disengaged from the fastening hole. The fastening hole is locked by fitting the fastening hole around the fixing shaft portion while an edge of the fastening hole rides over the retaining portion by elastic deformation thereof.

摘要： A developer accommodating unit includes a developer container provided with an opening at a lower portion thereof with respect to a direction of gravitation in an attitude during use and configured to accommodate a developer; a developer carrying member mounted at the opening and configured to carry the developer; and a feeding member provided in the developer container and configured to feed the developer in the developer container toward the developer carrying member. The feeding member is swingable about a predetermined supporting point as a swing center and is configured so that maximum acceleration when the feeding member moves toward the developer carrying member is smaller than maximum acceleration when the feeding member moves away from the developer carrying member.
