摘要： A powder supply device that includes a powder reservoir including a rotator having a rotation shaft, to store powder supplied from a powder container; and a powder amount detector. The powder amount detector includes a detected member disposed in the powder reservoir, a contact member attached to the rotation shaft, to contact the detected member to vibrate or move the detected member, a detector to detect vibration or a displacement of the detected member, and a detection result processor to detect the amount of the powder in the powder reservoir based on detection by the detector. The powder supply device further includes a controller to supply the powder from the powder container to the powder reservoir based on detection by the powder amount detector. The controller rotates the rotator in discharging the powder from the powder reservoir and supplying the powder from the powder container to the powder reservoir.

摘要： A powder container includes a powder chamber for containing powder for forming images, a powder outlet formed in a face of the powder container, and a shutter assembly to open and close the powder outlet and including first and second shutters. The first shutter is movable between a sealing position to close the powder outlet and an open position to open the powder outlet and includes a pressed member to cancel retention of the first shutter at the sealing position. The second shutter includes a pressing projection that interferes with the pressed member of the first shutter and is movable between a shielding position to cover the pressed member without interference between the pressing projection and the pressed member and a releasing position to press the pressed member with the pressing projection.

摘要： A development device includes a developer bearer, a developer regulator to adjust an amount of developer on the developer bearer, a supply compartment adjacent to the developer bearer across a side wall formed monolithic with the development casing using an identical material, a developer supply member to transport developer in the supply compartment in an axial direction, and a channel forming member having higher rigidity than that of the side wall. The channel forming member defines, with the side wall, a supply route extending over an entire development range, through which developer moves from the supply compartment to the developer bearer, and defines, with an inner wall of the development casing, a collecting route through which developer blocked by the developer regulator is collected in the supply compartment. Both axial end portions of the channel forming member are supported by the development casing.
