摘要： A developing unit includable in a process cartridge and in an image forming apparatus includes a developer bearing member including a magnetic field generator and a 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 poles to generate respective magnetic forces for removing the developer from the developer bearing member after the developer passes the development region. The second magnetic pole generates a magnetic force to attract the developer to form a magnetic brush on the developer bearing member. The developer regulating member includes a magnetic member outwardly disposed on an exterior perimeter surface of the developer bearing member upstream from the developer regulating member, and one planar surface of the magnetic member faces the second magnetic pole across an effective development region.

The developing unit includes a developer bearing member to bear developer including toner and carrier, a casing forming a developer container containing the developer, a screw having a shaft with a spiral screw blade, a toner density sensor to detect a density of the toner on a detection surface, and a detection surface agitating member fixedly mounted on the shaft of the screw at a position facing a detection surface to scrape away the developer accumulated on the detection surface as the screw rotates. The detection surface agitating member includes an elastic sheet elastically deformable to scrape away the developer accumulated on the detection surface and disposed at a substantially same angle to an axial direction of the shaft of the screw as the spiral screw blade.

摘要： A toner container includes a longitudinal container body, a held portion, and an electric component. The longitudinal container body has a first end and a second end distal to the first end in a length direction of the container body. The held portion is attached to the first end of the container body and configured to be detachably attached to the toner-container holder. The held portion includes a toner outlet for discharging the toner. The electric component electrically communicates with a component in the main body to detect whether the toner container is operatively set in the toner-container holder. The electric component is attached to the held portion such that when the held portion is attached to the toner-container holder the electric component is located above the toner outlet with respect to a vertical direction.
