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 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 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.
