Abstract
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.
