Abstract: A support member that supports an elastic member constituted of an elastic body contacting the surface of an image bearing member has a first surface that extends in a rotation axis direction of the image bearing member, and a second surface that includes a normal vector, which intersects with a normal vector of the first surface, and extends in the rotation axis direction. In the rotation axis direction, the first surface is fixed to two fixed portions of the frame, and a first vibration absorbing member is disposed between the two fixed portions so as to contact the frame and the first surface.

Abstract: A developer accommodating unit for accommodating a developer for image formation. A flexible container includes a developer accommodating portion for accommodating the developer and an opening for permitting discharge of the developer. The flexible container also includes a superposed multi layer sheet structure portion for forming the developer accommodating portion. A sealing member seals the opening and an unsealing member moves the sealing member to unseal the opening. A frame that accommodates the flexible container, the sealing member, and the unsealing member includes a fixing portion for fixing the flexible container. A fixed portion fixed to the fixing portion is provided at the superposed multi layer sheet structure portion of the flexible container, and an interlayer bonding portion between the superposed layers is provided between the fixed portion of the multi layer sheet structure portion and the developer accommodating portion.
