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： An image forming apparatus has a charge removing unit (31) between a transfer roller (11) for transferring a toner image from a surface of a photosensitive drum (4) to a transfer member and a charging unit (3) for electrostatically charging the surface of the photosensitive drum (4) approximately uniformly, with respect to a rotation direction of the photosensitive drum (4). The charge removing unit (31) includes LEDs (311) to irradiate the surface of the photosensitive drum (4) with charge-removing light. A support (312) supports the LEDs (311) approximately in a line along an axial direction of the photosensitive drum (4). A position setting mechanism (313) allows a position of the support (312) to be changed selectively in a direction orthogonal to the axis of the photosensitive drum (4). Thus, the image forming apparatus can suppress uneven charge-distribution in the axial direction of the photosensitive drum (4).

摘要： An image forming apparatus uses a charging roller to charge the surface of a photosensitive member to a predetermined potential. A current detector detects charging current when the charging bias is applied. A bias corrector corrects the charging bias and a storage stores a target charging current value when the photosensitive member is charged to a required potential. The bias corrector performs two corrections. The first correction compares a charging current value with a stored target charging current value, and determines a new bias based on the comparison. The second correction determines whether the bias obtained by the first correction is at a predetermined level or a higher level, and when the corrected charging bias is at the higher level, changes the target charging current value in accordance with the corrected charging bias and obtains a new charging bias on the basis of the changed target charging current value.
