摘要： A developing device includes a developer bearer including a magnetic field generator, a developer regulator disposed opposite the developer bearer across a regulation gap, a developer containing compartment disposed below the developer bearer, and a conveying screw disposed in the developer containing compartment and including a shaft having a diameter greater than a radius of the conveying screw. On a cross section perpendicular to an axial direction of the conveying screw, a developer scooping pole of the magnetic field generator to scoop the developer from the developer containing compartment onto the developer bearer is disposed between the regulation gap and a bisector dividing an angle extending from a first line, which connects a center of the developer bearer and a center of the conveying screw, to a second line, which connects the center of the developer bearer and the regulation gap, in a rotation direction of the developer bearer.

摘要： A developing device includes a casing to contain developer and define a developer circulation passage, a developing roller to bear the developer, and at least one developer conveyor to convey the developer. The developer conveyor is disposed in the developer circulation passage and lower than the developing roller. The developing device satisfies M1/L2>0.56 g/cm and M1/M2>0.50, where M1 represents an amount of developer borne on the developing roller, L1 represents a width in which the developing roller bears the developer in a longitudinal direction of the developing roller; and M2 represents an amount of developer stored in the casing and excluding the amount of developer borne.

摘要： A powder container includes: a powder containing unit that contains powder and at least a part of which is deformable; a discharging unit that receives the powder supplied from an opening of the powder containing unit via an inlet arranged on the discharging unit and discharges the powder to a supply destination; an elastic member that is arranged on a periphery of the inlet of the discharging unit; and a seal member that is arranged on the powder containing unit and seals the opening. The seal member is sandwiched between the discharging unit and the powder containing unit via the elastic member such that the seal member is removable from between the discharging unit and the powder containing unit.

摘要： An abnormality detection device is configured to detect abnormality in a subject to be driven by a motor via a drive transmission member. The abnormality detection device includes an output signal acquisition unit, a rotational frequency acquisition unit, and a determining unit. The output signal acquisition unit is configured to acquire a rotational frequency output signal output from the motor. The rotational frequency acquisition unit is configured to acquire a motor rotational frequency calculated from the rotational frequency output signal acquired by the output signal acquisition unit. The determining unit is configured to distinctively determine abnormality in the subject to be driven and abnormality in the motor based on the rotational frequency output signal acquired by the output signal acquisition unit and the motor rotational frequency acquired by the rotational frequency acquisition unit.

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.
