    摘要： A developing device developing a latent image on a latent image carrier with a developer, and including a casing having an opening facing the latent image carrier and a developer carrier. Also included is a magnetic field generating device including a first magnetic pole generating a magnetic field causing the developer to rise on the developer carrier in a form of a magnet brush in a developing region, and a second magnetic pole generating a magnetic field at a downstream side of the first magnetic pole in a rotating direction of the developer carrier. Further, a toner-scattering restraining device is provided on an end portion of the casing at the downstream side of the developing region, and a magnetic member provided on a side of the toner-scattering restraining device facing the latent image carrier. A peak of a magnetic flux density set by the second magnetic pole in its normal direction is located outside of the opening.

    摘要： A developing device includes a developer bearing member including an internal magnetic field generating device and configured such that a surface thereof moves to carry and convey a developer including toner and carrier. A developer regulating member regulates a quantity of the developer carried and conveyed by the developer bearing member toward a developing area, and a developer accommodating unit accommodates the developer regulated to be conveyed toward the developing area by the developer regulating member. A toner accommodating unit includes a toner supplying opening opposing a surface of the developer bearing surface of the developer bearing member at a position adjacent to and upstream of the developer accommodating unit in a developer conveying direction. The toner in the toner accommodating unit is taken into the developer on the developer bearing member based on a toner density of the developer on the developer bearing member by a movement of the developer with a conveyance of the developer on the developer bearing member. The developing device further includes a peeling off member that opposes, without contacting, a surface of the developer bearing member in the developer accommodating unit so as to peel off an upper layer part of the developer carried and conveyed by the developer bearing member.

    摘要： A toner container and an image forming apparatus are disclosed. The toner container includes a guiding member formed at a part surrounding a toner outlet to be protruded from a circumferential surface of the toner container for guiding an opening or closing operation of a shutter member in a circumferential direction of the toner container. The image forming apparatus includes an image forming apparatus main body. The image forming apparatus main body includes a main body side shutter for opening or closing a toner supplying opening to be connected to the toner outlet. When the shutter member is opened, an end surface of the guiding member pushes the main body side shutter together with the opening operation of the shutter member, and the toner supplying opening is opened and is connected to the toner outlet.
