Abstract
A developer container includes a frame having a developer storage chamber which stores a conveying member, a developing chamber in which a developer bearing member and a supplying member are arranged, a partition partitioning the developer storage chamber and the developing chamber and provided with a first opening, and a second opening which connects an interior of the developing chamber and an exterior of the frame. A filter allows passage of air and restricts passage of the developer, with the filter being fixed to the frame so as to cover 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, and the conveying member conveys the developer such that the developer passes above the supplying member.
