    摘要: An image forming apparatus includes at least one image carrier and a recording medium conveyor forming a transfer nip therebetween, a conveyance member disposed closest to the transfer nip on an upstream side of the transfer nip to convey the recording medium to the transfer nip, and a conveyance control mechanism to deactivate the conveyance member to stop providing a conveyance force to the recording medium after the leading edge of the recording medium has entered the transfer nip and before the trailing edge of the recording medium passes a point of force application and remaining in the inactive state until the recording medium passes the point of force application. The conveyance force remains unapplied to the recording medium from when the conveyance control mechanism deactivates the conveyance member to when the trailing edge of the recording medium passes the transfer nip.

    摘要: A developing apparatus for use in an image forming apparatus includes a developer bearing member having a magnetic field generating device internally and configured to bear and convey two-component developer including toner and magnetic carrier, a first regulating member configured to regulate an amount of the developer born and conveyed by the developer bearing member, a developer container section for storing the developer scraped off by the first regulating member, a second regulating member arranged upstream of the first regulating member in a conveying direction of the developer on the developer bearing member, and a toner container section for supplying toner to the developer bearing member. The developing apparatus changes a toner take-in condition of the developer on the developer bearing member by changing a contact condition between the developer and the toner according to a change of a toner density of the developer on the developer bearing member. A surface of the second regulating member facing the developer bearing member has an area large enough to unify a layer thickness of the developer on the image bearing member in the axial direction of the developer bearing member.

    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.
