Abstract
A developing device includes a developing container, a rotatable member including a first screw portion and a second screw portion, a first feeding path configured to accommodate the first screw portion, a second feeding path provided in communication with the first feeding path at a position downstream of the second screw portion with respect to a develop feeding direction, and a developer discharging opening provided in the second feeding path. In a state in which the developing device is mounted to the image forming apparatus, in a cross section of the second feeding path perpendicular to a rotational axis of the rotatable member, the second feeding path includes a region where a distance between side surfaces of the second feeding path in a side above a center of a rotation shaft of the rotatable member with respect to a vertical direction increases upwardly.
