摘要：A developing unit includable in a process cartridge and in an image formingapparatus includes a developer bearing member including a magnetic field generator anda nonmagnetic hollow member, a developer container, an agitation/conveyance member,a developer regulating member to regulate the thickness of a layer of the two-component developer. The magnetic field generator has first and second magnetic polesto generate respective magnetic forces for removing the developer from the developerbearing member after the developer passes the development region. The secondmagnetic pole generates a magnetic force to attract the developer to form a magneticbrush on the developer bearing member. The developer regulating member includes amagnetic member outwardly disposed on an exterior perimeter surface of the developerbearing member upstream from the developer regulating member, and one planarsurface of the magnetic member faces the second magnetic pole across an effectivedevelopment region.
