摘要： A developing apparatus employing a three-pole stationary magnetic roller for use with a uni-component magnetic developer or toner. The apparatus includes a rotational sleeve which accommodates the stationary roller, a mixer disposed in a toner vessel for stirring the toner, and a toner layer thickness regulator disposed upstream in the sleeve rotation direction from the developing position at which the image on a photo-sensitive drum is developed. The magnetic roller has a developing pole located near the developing position, a blade-facing pole facing the toner layer thickness regulator, and a shield pole located downstream in the sleeve rotation direction from the developing position, where the blade-facing pole and the shield pole are of the opposite polarity to the developing pole. The blade-facing pole and the shield pole generate a repulsive magnetic field therebetween, where the toner that has been stirred in the vessel comes in contact with the sleeve.

摘要： A bias corrector conducts a first bias correction calculation by performing first through third calculations. The first calculation compares a stored target charging current value to a first charging current value detected when a first charging bias was applied by a bias applying device. The second calculation is performed repeatedly to calculate a second charging bias based on the comparison result and then to compare the target charging current value to a second charging current value detected by the current detector when the second charging bias was applied by the bias applying device. The third charging bias is calculated based on the comparison result. A second bias correction calculation then is conducted to correct the charging bias obtained as a result of the first bias correction calculation based on photoconductor information detected by a photoconductor information detector.
摘要翻译：偏置校正器通过执行第一至第三计算来进行第一偏置校正计算。第一计算将存储的目标充电电流值与通过偏置施加装置施加第一充电偏压时检测到的第一充电电流值进行比较。重复执行第二计算，以基于比较结果计算第二充电偏压，然后当偏置施加装置施加第二充电偏压时，将目标充电电流值与由电流检测器检测到的第二充电电流值进行比较。基于比较结果计算第三充电偏差。然后进行第二偏置校正计算，以基于由感光体信息检测器检测到的感光体信息来校正作为第一偏置校正计算的结果而获得的充电偏压。
