A developing device includes a developer bearing member, a regulating member configured to regulate an amount of the developer borne by the developer bearing member, and a toner seal member being in contact with a peripheral surface of the developer bearing member. The regulating member includes a flexible support member and a blade member supported by the support member and being in contact with the developer bearing member, an end portion of the regulating member more protrudes toward the developer bearing member than a central portion thereof in a rotation axial direction of the developer bearing member. The toner seal member is pressed along the rotation axial direction to the end portion of the regulating member in the rotation axial direction. |
