One end portion of the guiding portion is arranged above an upper end of the partition portion, and the other end portion of the guiding portion is arranged above a rotation axis of a conveyance screw in the second chamber and below an uppermost portion of the conveyance screw while leaving a clearance between the guiding portion and the conveyance screw.
