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the downstream developing roller has a most approachable surface that approaches closest to the image bearer and a most withdrawn surface that withdraws farthest from the image bearer.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of the upstream developing roller at the first developing position, the reference surface point opposes the most withdrawn surface of the downstream developing roller at the second developing position.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 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 conveyor includes a conveyance roller to convey a conveyed object, a pair of roller supports opposing to each other and supporting both ends of the conveyance roller in an axial direction thereof, a position sensor to detect a position of the conveyed object, and a sensor support supporting the position sensor. Each of the pair of roller supports has an insertion hole into which the sensor support is inserted. The insertion hole determines a position of the sensor support in a direction intersecting an insertion direction of the sensor support. The sensor support includes a positioning portion determining the position of the sensor support with respect to at least one of the pair of roller supports. The positioning portion determines the position of the sensor support in the insertion direction, a direction opposite to the insertion direction, and a rotational direction about an axis along the insertion direction.

摘要： A developing device includes a rotator that rotates around a shaft, and a bearing element that supports the shaft to a housing. A sliding element formed of a composite material that contains self-lubricating thermoplastic olefin resin as a base material is used as the bearing element. The sliding element formed of the composite material has at least a ratio of numerical values of “Rockwell hardness”/“bending elastic modulus” in a range from 25 to 45, and provides a sliding surface of which a frictional coefficient is lower than that of the sliding element formed of the base material.
