Abstract:
A developer storage container includes a container body, a shaft, a moving wall and a pressing member. The container body has an inner peripheral surface defining a tubular internal space extending along a first direction. The shaft is arranged to extend in the first direction in the internal space and rotatably supported. The moving wall is movable in the first direction in the internal space while conveying the developer in the internal space toward a developer discharge port. The pressing member moves integrally with the moving wall by pressing the moving wall when the shaft is rotated in a first rotating direction and relatively moves to an upstream side with respect to the moving wall according to the engagement of a first engaging portion and a second engaging portion when the shaft is rotated in a second rotating direction opposite to the first rotating direction.

Claim (Index 7):
A developer storage container according to  claim 1 , wherein:\n the first engaging portion includes:\n a first inclined surface inclined to extend radially inward along the first direction; and \n a second inclined surface arranged on a side opposite to the first inclined surface across a ridge of the first engaging portion, inclined to extend radially outward along the first direction, and more gently inclined than the first inclined surface; \n the second engaging portion is a spiral projection and includes: \n a third inclined surface inclined to extend radially inward along the first direction; and \n a fourth inclined surface arranged on a side opposite to the third inclined surface across a ridge of the second engaging portion, inclined to extend radially outward along the first direction, and more gently inclined than the third inclined surface; and \n a rotational torque applied to the shaft according to the engagement of the second inclined surface of the first engaging portion and the fourth inclined surface of the second engaging portion when the shaft is rotated in the second rotating direction is larger than a rotational torque applied to the shaft according to the engagement of the first inclined surface of the first engaging portion and the third inclined surface of the second engaging portion when the shaft is rotated in the first rotating direction.
