摘要： A corona and associated electrical drive as shown herein, neutralize the static charges on non-conductive sheets or webs. The neutralization of static charge is accomplished by passing the material to be neutralized under a double wire corona. Both wires in the corona are connected to an AC signal. The AC signal drives both wires with a signal that alternates in polarity at frequency f. The wires are spaced apart a predetermined distance calculated from a function dependent upon the frequency of the AC signal and the speed of the paper moving under the corona wires. The predetermined distance is such that a given area of the paper will pass under one wire at a first polarity and under the second wire at the opposite polarity. Further enhancement of neutralization can be accomplished by using a second double wire corona out of phase with the first double wire corona. In addition the sheet or web as it passes under the corona wires is supported to prevent static charge on the support from balancing a static charge on the sheet or web. Accordingly, the only static charge present as the sheet or web moves under the corona is that charge carried by the sheet or web. The corona wires will neutralize that charge either by discharging it with oppositely charged ions or depositing oppositely charged ions to balance the charge already on the sheet or web. Thus as the sheet or web moves away from the neutralizing station the sheet or web has a net charge which is substantially zero.
摘要翻译：如本文所示的电晕和相关的电气驱动器，中和非导电片材或网片上的静电荷。静电荷的中和是通过在双线电晕下通过要被中和的材料来实现的。电晕中的两根线连接到交流信号。交流信号用频率f交替极性的信号驱动两根导线。电线按照取决于AC信号的频率和在电晕丝下移动的纸张的速度的函数计算出的预定距离。预定距离使得纸张的给定区域将以相同极性的第一极性的第一导线下方的第一导线下方通过。通过使用与第一双线电晕相异相的第二双线电晕可以进一步增强中和。此外，在通过电晕丝之下的片材或纤维网被支撑以防止支撑体上的静电荷平衡片材或纤维网上的静电荷。因此，在电晕下移动的片材或纤维网中存在的唯一静电荷是由片材或纤维网承载的电荷。电晕丝将通过以相反电荷的离子放电或沉积相反电荷的离子来平衡电荷已经在片材或纤维网上来中和该电荷。因此，当纸张或纸幅远离中和站时，纸张或纸幅具有基本为零的净电荷。

摘要： A device adapted for use with electrophotographic image forming apparatus of the type in which the spacing between the voltage impressing station and the developing station for the recording sheet is smaller than the length of the recording sheet. The device is effective to reduce the voltage being impressed on an electrically conducting layer of the recording sheet substantially to the level of the ground potential or reference voltage immediately before the developing station by first impressing on the electrically conducting material layer of the recording sheet a bias voltage of opposite charge to a bias voltage impressed on the layer in the voltage impressing station on the upstream side of the developing station and then alternatingly impressing bias voltages of alternately varying polarities and successively decreasing absolute values on the electrically conducting material layer of the recording sheet, so as to improve the conditions under which the recording sheet is developed.

摘要： In a cartridge, a housing has a developer accommodating portion and includes a first side wall and a second side wall. A coupling member is disposed at a position opposite to the developer accommodating portion with respect to the first side wall. A detection body is disposed at a position opposite to the developer accommodating portion with respect to the second side wall. A first driving force transmission member is positioned at the same side with the coupling member with respect to the first side wall, and transmits driving force from the coupling member to a rotating member. A second driving force transmission member is positioned at the same side with the detection body with respect to the second side wall, and transmits driving force from the rotating member to the detection body.

摘要： An image forming device includes an image forming unit, a roller unit, a static elimination brush, a moving unit, and a control unit. The static elimination brush eliminates static electricity of the printing medium. The moving unit moves the static elimination brush between a first position that does not intersect a first conveyance path on a downstream side of the roller unit in the conveyance path and a second position that intersects the first conveyance path. The control unit controls the moving unit during the conveyance of the printing medium, positions the static elimination brush at a position different from the second position until a front end of the printing medium passes an intersection position at which the static elimination brush and the first conveyance path intersect if the static elimination brush is positioned at the second position, and moves the static elimination brush to the second position after the front end of the printing medium passes the intersection position until a rear end of the printing medium passes the intersection position.
