A controller executes an operation in a mode in which after the developer accommodating portion starts to be unsealed at the sealing member, the feeding screw is initially rotated for a predetermined period in a direction opposite to a normal direction in which the feeding screw is rotated during the image forming operation, and after elapse of the predetermined period, the feeding screw is rotated in the normal direction.
