Abstract: A longitudinal end portion of an opposing magnetic member of a developer supporting rotator is positioned more longitudinally outside than a longitudinal end portion of a toner supporting side magnetic member. With respect to the opposing magnetic member facing the toner supporting side magnetic member and a downstream magnetic member disposed more downstream than the opposing magnetic member in a rotational direction, a magnetic force generated in a vicinity of both longitudinally end portions thereof is greater than a magnetic force generated longitudinally inside thereof. A housing includes a sealing portion that projects from a position facing a face at a longitudinal end portion of the developer supporting rotator toward the face, such that the sealing portion prevents the toner in a space between the face and an inner face of the housing from scattering outside.

Abstract: An image forming apparatus includes a developer storage portion, a developing roller, a magnetic force generating portion, and an image carrying member. The magnetic force generating portion is provided in the developing roller and generates a magnetic force for keeping the developer on an outer circumferential surface of the developing roller. The image carrying member is disposed to face the developing roller across a predetermined developing gap, is rotationally driven, receives the toner from the developer supplied to the developing gap by the developing roller, and keeps a toner image on an outer circumferential surface of the image carrying member. The image forming apparatus, during non image formation, supplies a more amount of developer to the developing gap than an amount of developer for developing supplied to the developing gap during image formation such that the outer circumferential surface of the image carrying member is cleaned.

Abstract: A developer replenishing apparatus includes a developer housing container and a sensor. The developer housing container includes a container main body having a wall that partitions an internal space, a shaft section arranged so as to extend in a first direction in the internal space, a moving wall which moves from an upstream side to a downstream side in the first direction along the shaft section and which conveys the developer, and a developer discharge port which is arranged near a downstream end in the first direction of the container main body. The sensor is arranged at a position that enables the sensor to generate different outputs between before and after the moving wall reaches a prescribed position on a movement route. The determining unit determines a state where there is no developer in the developer housing container when the sensor generates an output determined in advance.

Abstract: An image forming apparatus has a developing device and a controller. The developing device includes a stirring member, rotatable at a first speed or at a second speed lower than the first speed, which varies, according to its speed, the amount of developer discharged out of the developing device. The controller drives the stirring member to rotate at the second speed, then switches the rotation speed of the stirring member to a third speed higher than the second speed but lower than the first speed, and then drives the stirring member to rotate at the third speed for a first period. The third speed is set higher the lower the fluidity of the developer.

Abstract: A developing device includes a developing container, a first stirring and conveying member, a second stirring and conveying member, a developer replenishing port, a developer discharging portion, a developing roller, a toner supply roller, a regulating blade, a toner receiver member, and a vibration generating device. The developing device is capable of executing a toner collecting mode in which the vibration generating device vibrates the toner receiver member so that toner deposited on the toner receiver member is shaken off by vibration and is collected into the second conveying chamber, in the non-image formation period. The developing device is capable of executing a forced discharge mode in which developer containing the collected toner collected from the toner receiver member into the second conveying chamber is forcibly discharged from the developer discharging portion to outside of the developing container, after the toner collecting mode is executed.
