A developing device includes a developing unit, swingably supported, for supplying a developer to an image bearing member, and including an inwardly extending wall portion. In an attitude during use, when against an urging force of an urging member configured to urge the developing unit in a first direction toward the image bearing member, the developing unit is moved in a second direction opposite to the first direction, the inwardly extending wall portion is contactable to a restricting member for restricting an amount of movement of the developing unit in the second direction.
