Abstract
A developing apparatus includes a developer bearing member configured to bear a developer on a surface, a regulating member that regulates layer thickness of the developer on the developer bearing member, and a development chamber provided with the developer bearing member and the regulating member and having an opening. A storage chamber stores the developer, and a conveying member in the storage chamber conveys the stored developer to the development chamber through the opening. The developing apparatus collects, after the developer on the image bearing member is transferred onto a transfer material, the developer remaining on the image bearing member into the storage chamber, wherein a bottom section of the development chamber is located above a bottom section of the storage chamber in a vertical direction. A contact region of the developer bearing member in contact with the regulating member is located directly above the opening in the vertical direction.
