In order to achieve the above object, a developing container according to the present invention comprises:
A developer carrier for carrying the developer;
A conveying member for conveying the developer;
A frame for storing the developer,
A developer storage chamber for storing the conveying member;
A developing chamber in which the developer carrying member is disposed;
A partition for partitioning the developer storage chamber and the development chamber, wherein the developer storage chamber and the development chamber communicate with each other, and the developer conveyed from the developer storage chamber to the development chamber is allowed to pass therethrough; A partition provided with a first opening;
A second opening communicating the inside of the developing chamber and the outside of the frame body in an orthogonal direction orthogonal to the direction of the rotation axis of the transport member;
A frame provided with,
A sealing member that suppresses leakage of the developer from between the frame and the developer carrier;
Allows the air going out through, a filter that restricts the developer going out through a second filter that is fixed relative to the frame so as to open the cover,
Have
The transport member is deformable, and the developer is transported from the developer storage chamber to the development chamber through the first opening by releasing the deformation of the transport member. .
