摘要： A developer bearing member on which grooves slanting in a thrust direction of the developer bearing member cross other grooves reversely slanting relative to the thrust direction, wherein each of the grooves and the reversely slanting grooves is slanting at an angle of greater than 0° and not greater than 40°. Any two adjacent intersections of the grooves and the reversely slanting grooves in the thrust (or peripheral) direction are preferably on different levels in the peripheral (or thrust) direction. The distance between two adjacent intersections in the thrust direction is preferably from 1.3 mm to 4.8 mm. The distance between two adjacent intersections in the thrust direction is preferably from 0.38 Vd/Vi (mm) to 1.1 Vd/Vi (mm). The deviation in depth of grooves present on a 36° arc surface portion of the member is not greater than 15% of the gap between the image bearing member and the developer bearing member.

摘要： A developing device for an image forming apparatus includes a developer carrier such as a developing sleeve having a magnetic field generating device therein which carries and conveys a developer containing toner and magnetic carrier particles. The developing device also includes a first regulating member such as a blade which regulates the developer being carried and conveyed by the developer carrier, and a developer storing section stores developer scraped off the developer carrier by the first regulating member. The developer storing section includes a second regulating member arranged upstream of the first regulating member with respect to a direction in which the developer carrier conveys the developer. The developing device further includes a toner storing section provided adjacent to the developer storing section to supply toner to the developer carrier. A contact condition of the developer carried on the developer carrier with the toner supplied to the developer carrier from the toner storing section is varied in accordance with variation of a toner density in the developer carried on the developer carrier to thereby vary a condition of the developer on the developer carrier to attract the toner. The second regulating member is spaced from the developer carrier such that when a thickness of a layer of the developer on the developer carrier increases due to an increase of the toner density in the developer on the developer carrier, the second regulating member regulates an increased amount of the developer being carried and conveyed by the developer carrier. The magnetic fields, toner speeds, and distances of the regulating members to the developer carrier satisfy predetermined conditions in different embodiments.

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.
