摘要： PROBLEM TO BE SOLVED: To keep the surface potential of an image carrier optimum by correcting a voltage applied to a charging member so as to match use conditions such as an environmental condition, a throughput per unit, and a processing condition. SOLUTION: Each time a photoreceptor drum is rotated one time, a charge amount is corrected to increase, thereby making it possible to keep the charge amount flatter. Also, in view of an increase in an amount of recovery of the charge amount with an increase in rest time per cycle, the amount of recovery, ΔV, is calculated based on the rest time (also based on cycle and environment), and the degree of reset is adjusted. This prevents the charge amount from exceeding, in particular, the upper limit serving as a threshold at which scattering of developer (carrier) is caused. In addition, the correction amount of charge increase is prevented from being reset due to a short rest time. This prevents the charge amount from falling below the lower limit serving as a threshold at which fog is caused. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：通过校正施加到充电部件的电压，以便匹配诸如环境条件，每单位吞吐量和处理条件的使用条件，使图像载体的表面电位最佳化。
解决方案：每次感光鼓旋转一次时，电荷量被校正增加，从而使得可以保持电荷量更平坦。此外，考虑到随着每个周期的休息时间的增加，电荷量的恢复量的增加，基于休息时间（也基于周期和环境）计算恢复量ΔV，调整复位度。这防止了充电量超过特别是作为引起显影剂（载体）散射的阈值的上限。此外，由于休息时间短，防止了电荷增加的校正量复位。这防止了充电量低于作为引起雾的阈值的下限。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce processing load for correcting a voltage applied to an electrifying roll. SOLUTION: In an image forming processing state 90, throughput is counted. When the image forming processing state is completed, a cumulative correction counter is updated based on a count value A. When a cleaning processing state is completed, the cumulative correction counter is updated based on a count value B. Further, in completing a standby state 94, when a count value T at that time reaches a threshold value Tth, the count value S of the cumulative correction counter is reduced according to the count value T, the set value of the voltage applied to the electrifying roll is corrected based on the count value S obtained by this and image forming processing is performed based on the set value.
