Abstract
The developing device includes a development container, a developer carrier, and a restricting blade. The development container has an opening. The developer carrier has a development area. The development container includes a pair of side frames, and a pair of side wall portions. In each of the pair of side wall portions, a seal member insertion hole extending through in the rotation-axial direction is formed at a position facing an end edge of the restricting blade in the rotation-axial direction. The developing device includes a blade-side side seal inserted in the seal member insertion hole to block a gap between the restricting blade and the side wall portion.
