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 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the downstream developing roller has a most approachable surface that approaches closest to the image bearer and a most withdrawn surface that withdraws farthest from the image bearer.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of the upstream developing roller at the first developing position, the reference surface point opposes the most withdrawn surface of the downstream developing roller at the second developing position.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 system includes a first developer carrier to carry and supply two-component developer including toner and carrier to a latent image formed on an image bearer. A first magnetic field generator having plural first magnetic poles is rotatably installed in the first developer carrier and causes the two-component developer to put forth ears and conveys the two-component developer on the developer carrier. A cross-sectional center of the first magnetic field generator is deviated from that of the first developer carrier toward the image bearer by a prescribed length. A developer peel-off device including a second magnetic field generator is provided in the vicinity of the surface of the first developer carrier to peel off the developer not supplied to the image bearer and remaining on the surface of the first developer carrier.

摘要： A developing device capable of preventing scattered developer from being discharged and of stably supplying a developer to a latent image carrier by preventing the developer from being discharged despite that the amount of developer within the developing device is not increased, and an image forming apparatus including the developing device. When the bulk of the developer existing in the vicinity of the downstream end in the conveyance direction of the supply conveyance path exceeds the height level of the developer discharge port, the developer that has reached the height level of the developer discharge port is discharged to the outside of the developing device by the developer discharge port and developer conveyance path serving as the developer discharge device.

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.

摘要： An information processing device is provided in which a valid initial program is transferred to a RAM while avoiding a invalid block which is present in a low reliable storage device, such as a NAND-type flash memory or the like. A management information storing section 29 stores management information 30 indicating a position of a invalid block in a first storage device 31. When an information processing device 1 is powered on, a transfer determination section 20 is controlled to read a BSP 26 from a valid block of a first storage device 11 based on the management information 30, and transfer the BSP 26 to a second storage device 32. Thereby, it is possible to avoid reading of a invalid block present in the first storage device 31.
