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 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 plurality of conveyance passages, an opening portion, and a filter. Developer is conveyed in the plurality of conveyance passages in a longitudinal direction of the developing device. The opening portion is disposed in one conveyance passage of the plurality of conveyance passages and communicates with an outside of the developing device. The filter is fitted in the opening portion and has both a collecting ability to collect the developer and a ventilation ability to ventilate the one conveyance passage to the outside of the developing device. The collecting ability of the filter is higher in a high-bulk portion in which bulk of the developer increases in the one conveyance passage than in a low-bulk portion in which the bulk of the developer decreases in the one conveyance passage. The ventilation ability of the filter is lower in the high-bulk portion than in the low-bulk portion.
