摘要： An image forming apparatus includes a photosensitive member, a charging member, an exposing device, a developing device, a transfer member, a brush, a voltage applying portion, and a control portion controlling a surface potential of the photosensitive member at the brush contacting position. When a value of subtracting a value of the surface potential of the photosensitive member in the brush contacting position from a value of the brush voltage is defined as a contacting position potential difference, the control portion controls the surface potential of the photosensitive member in the brush contacting position so that the contacting position potential difference is changed from a first potential difference to a second potential difference in a predetermined direction which is either one of an increasing direction or a decreasing direction, and then the contacting position potential difference is changed from the second potential difference to a third potential difference in the predetermined direction.

摘要： A system for optimization of a regeneration schedule for a contact cleaning roller (CCR) used to remove particles from a substrate surface by being rolled along the substrate surface. In rolling along the surface, the CCR leaves a residual static charge. The level of leaving charge is sensed by a fieldmeter. When a CCR is first placed into service against a substrate, the leaving charge level is greater than the entering static charge level on the substrate ahead of the CCR. The entering charge is sensed by another fieldmeter, and the charge differential is determined and monitored. As the CCR becomes progressively loaded with particles during service, the leaving charge progressively diminishes. Thus the charge differential indicates inversely the particle loading of the CCR such that a charge differential limit can be set, below which the roller is removed from service and renewed by cleaning.
摘要翻译： 一种用于优化用于通过沿衬底表面滚动从衬底表面去除颗粒的接触式清洁辊（CCR）的再生计划的优化系统。 在沿表面滚动时，CCR留下残留的静电荷。 离地电荷的电平由场仪感测。 当CCR首先投入使用于衬底时，离开电荷水平大于CCR前面的衬底上的进入静电电平。 进入的电荷由另一个场仪测量，并且电荷微分被确定和监测。 由于CCR在服务期间逐渐加载颗粒，所以离开的费用逐渐减少。 因此，电荷微分相反地表示CCR的颗粒负载，使得可以设定电荷微分极限，低于该值时，辊从使用中移除并通过清洁更新。

摘要： An image forming apparatus includes a latent-image carrier, a developing unit, a transfer unit, a cleaning unit, a recovered-toner supply unit, and a foreign-matter collecting unit. The developing unit carries a developer containing a toner and develops an electrostatic latent image on the latent-image carrier with the toner. The transfer unit transfers the toner developed on the latent-image carrier to a recording material directly or via an intermediate transfer body. The cleaning unit removes a toner remaining on at least one of the latent-image carrier and the intermediate transfer medium after the transfer. The recovered-toner supply unit supplies a toner removed by the cleaning unit to the developing unit again. The foreign-matter collecting unit collects a foreign matter, which is mixed into the toner supplied from the recovered-toner supply unit and moved onto the latent-image carrier by the developing unit, before the transfer by the transfer unit.
