摘要： A developing device includes a casing to contain developer, a developer bearer, an upper and lower developer conveyors to convey the developer to one side in an axial direction of rotation shafts thereof, a communicating portion disposed on a first end side on which an input gear is disposed, to fall the developer from the upper developer conveyor to the lower developer conveyor, bearings to receive end portions the upper and lower developer conveyors, and first and second end seals to seal gaps in the bearings on the upper and lower developer conveyors, respectively. The first end seals and the second end are disposed on the first end side and a second end side, respectively. A sliding friction between the rotation shaft and at least one of the first end seals is smaller than a sliding friction between the rotation shaft and the second end seal.

摘要： A developing device includes a developer bearer, a casing defining an upper compartment to contain the developer and a lower compartment disposed lower than the upper compartment, to contain the developer, and a first conveyor and a second conveyor disposed in the upper compartment and the lower compartment, respectively, to convey the developer in a longitudinal direction of the developer bearer and circulate the developer between the upper compartment and the lower compartment through a first communicating opening, through which the developer is conveyed upward, and a second communicating opening. A developer-lifting range of the upper compartment, which opposes the first communicating opening, is larger in volume than a developer-lifting range of the lower compartment. One of the upper compartment and the lower compartment is disposed adjacent to the developer bearer to supply the developer to the developer bearer.

摘要： A developing device includes a developer bearer, a magnetic field generator, a casing having an opening, a developer conveyor to rotate inside a developer containing compartment below the developer bearer, and a developer regulator. A side wall of the casing defines a bottom end of the opening, and the developer regulator is disposed on the side wall. The side wall includes an upper end face facing the developer bearer below an axis of the developer bearer and a curved inner face along an orbit of rotation of the developer conveyor, extending from below the developer conveyor toward the upper end face. On a virtual plane perpendicular to the axis of the developer bearer, an intersection between a tangent line to an upper end of the curved inner face and the surface of the developer bearer is in a range from a tangential magnetic-flux peak and a closest approach point.

摘要： A development device includes a developer bearer to carry by rotation developer to a development range facing a latent image bearer, and a developer regulator to adjust an amount of developer transported to the development range by the developer bearer. Multiple projections are formed in a surface of the developer bearer, and the developer bearer rotates in a reverse direction to a direction of rotation for image development while image development is not performed. The developer regulator includes a blade having a first end held by a regulator holder and a second end that contacts the multiple projections formed in the surface of the developer bearer and is disposed in a direction counter to the direction of rotation of the developer bearer for image development.

摘要： A removable device is removably attachable to an image forming apparatus main body. The removable device includes an information storage device, a holder, and a low frictional structure. The information storage device includes: an information storage unit that stores information to be communicated between the apparatus main body and the removable device; a terminal to be contacted with an apparatus main-body terminal, for communicating information with the apparatus main body; and a substrate that holds the information storage unit and the terminal and that includes a guide to be fitted to a protrusion provided on the apparatus main body. The holder holds the substrate such that the substrate can move, when the removable device approaches the apparatus main-body terminal, on a virtual plane intersecting with a moving direction of the removable device. The low frictional structure is arranged on a contact area between the substrate and the holder.

摘要： A development device includes a development casing, a developer bearer, a first developer conveyance member to supply developer to the developer bearer, a second developer conveyance member to transport developer axially, and a partition dividing an interior of the development casing into a supply channel and a collecting channel via which developer received from a downstream end portion of the supply channel is forwarded to an upstream end portion of the supply channel. The supply channel includes a conveyance area and a buffer area disposed adjacent to the conveyance area in a direction perpendicular to an axial direction to temporarily retain developer and midway in the developer conveyance direction inside the supply channel, and an upstream end face defining an upstream end of the buffer area is inclined relative to the axial direction to draw away from the conveyance area downstream in the developer conveyance direction.
