description A developing device (100) to supply toner in a developer, including a development member (1) that attaches the developer to an outer circumferential surface of the development member (1) and supplies the toner to the image bearing member (10), a first regulation member (2) including a first regulating portion (21) that forms a first doctor gap (DG) between the outer circumferential surface of the development member (1) and the first regulating portion (21), and a second regulation member (5) disposed on an upstream side of the first regulation member (2) in a rotational direction of the development member (1) and includes a second regulating portion (51) that forms a second doctor gap (G) between the outer circumferential surface of the development member (1) and the second regulating portion (51), the second doctor gaps (G) at a central portion and both end portions in a longitudinal direction of the development member (1) being different from each other.
