摘要： A cleaning device includes a brush roller configured to contact an image bearer while rotating to remove toner adhering to an image bearer, a bias applying device configured to apply a bias to the brush roller, and control circuitry configured to causes the bias applying device to apply a first bias in a first period from when the brush roller is new to when a cumulative travel distance or a cumulative rotation time of the brush roller reaches a predetermined value, and to apply a second bias in a second period after the first period. The first bias sends a first current through the brush roller, and the second bias sends a second current through the brush roller. The absolute value of the first current is smaller than the absolute value of the second current.

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.
