    摘要： Provided is an elastic member which is obtained by forming a resin coating layer on at least a part of the surface of a base that is formed of an elastic material, and which is characterized in that the resin coating layer is a coating film that contains 1.5-45 parts by mass of a low-friction powder per 100 parts by mass of a base resin and has a 100% modulus of 22-30 MPa. This elastic member has a resin coating layer that has a good balance between film formability and low friction, and is suitable as a sealing member for an opening part of a toner container that is provided on a toner cartridge of a printer, a copy machine or the like.

    摘要： A developer container includes a developer storage chamber that stores developer and includes an opening, a sealing member that seals the opening, an unsealing member that opens the opening by rotating such that the sealing member, a part of which is attached to the unsealing member, is peeled away, a stirring member that is attached to the unsealing member; and a regulating portion that regulates rotation of the unsealing member by contacting the stirring member. The regulating portion is provided to regulate the rotation of the unsealing member when the developer container receives an external force, and allow the unsealing member to rotate such that the opening is opened when the unsealing member receives driving power.

    摘要： An image developing apparatus includes a developer carrying sleeve; a first developer chamber; a second developer chamber; a developer feeding screw in the first chamber; a first port for moving the developer from the first chamber to the second chamber; a second port for moving the developer from the second chamber to the first chamber; a supply opening for supplying the developer into the first chamber; a discharge opening adjacent to the second port for discharging the developer from the first chamber; a developer accommodating portion in the first chamber; and a controller for executing, after the developer is supplied from the developer accommodating portion, a operation in a mode in which the feeding screw is rotated for a time period in a direction opposite to a normal direction in which the feeding screw is rotated during the image forming operation and then is rotated in the normal direction.

    摘要： 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.
