    摘要： A toner bottle driving device control method includes driving one of multiple toner bottle driving devices connected to a single toner container at a time, detecting abnormality of a toner bottle driving device being driven, determining a first abnormality phase of the toner bottle driving device being driven when a number of times the abnormality is detected exceeds a threshold, inhibiting the toner bottle driving device being in the first abnormality phase from driving until the first abnormality phase is resolved, driving a drivable toner bottle driving device containing a non-empty toner bottle when the toner bottle contained in the toner bottle driving device being driven is determined as empty, determining that the multiple toner bottle driving devices are in a second abnormality phase when each of the multiple toner bottle driving devices is determined as being in the first abnormality phase, and inhibiting image formation.

    摘要： A developing device to develop a latent image on a rotatable image bearer includes an upstream developing roller disposed opposite the image bearer at a first developing position, and a downstream developing roller disposed adjacent to and downstream from the upstream developing roller in a direction of rotation of the image bearer, disposed opposite the image bearer at a second developing position. Each of the upstream developing roller and the downstream developing roller has a most approachable surface that approaches closest to the image bearer and a most withdrawn surface that withdraws farthest from the image bearer. In a state in which a reference surface point of the image bearer is disposed opposite the most approachable surface of the upstream developing roller at the first developing position, the reference surface point opposes the most withdrawn surface of the downstream developing roller at the second developing position.

    摘要： A developing unit includes a developer bearer to bear developer on a surface thereof, first and second developer conveyors each having a spiral blade mounted on a rotary shaft thereof parallel to a rotary axis of the developer bearer to convey developer in opposite directions to each other. A developer drain hole is provided at a given height in a side wall of a second developer conveyance channel to face a communication opening across the second developer conveyor. The first developer conveyor rotates in a direction with its spiral blade rising between the rotary shaft of the first developer conveyor and the communication opening. Rotational phases of the first developer conveyor and the second developer conveyor are fixed and synchronized with each other to weaken momentum of developer flow generated by the first developer conveyor toward the developer drain hole via the second developer conveyor.

    摘要： A toner supply device includes a toner container, a transport-path forming member, an opening, a shutter member, and a first seal member. The opening is provided at a side wall of the transport-path forming member. The shutter member is movable between a closed position to close the transport path by being inserted in the opening and an open position. The first seal member fills a gap between an inner wall of the opening and the shutter member in a toner transport direction in which the toner is transported through the transport path. When the shutter member is inserted in the opening, the shutter member is elastically deformable in a deformation direction perpendicular to both the toner transport direction and a moving direction of the shutter member, and when the shutter member is not inserted in the opening, the shutter member is wider than the opening in the deformation direction.
