Abstract
A developer container includes a developer bearing member for bearing developer, a conveying member which conveys the developer, and a frame. In the frame, a partition partitions a developer storage chamber and a developing chamber and includes a first opening which connects the developer storage chamber with the developing chamber, and a second opening which connects an interior of the developing chamber and an exterior of the frame. A sealing member suppresses leakage of the developer from between the frame and the developer bearing member, and a filter allows passage of air through the second opening and restricts passage of the developer through the second opening. The conveying member is deformable such that the developer is conveyed from the developer storage chamber to the developing chamber via the first opening by deformation of the conveying member being released.
