    • This invention relates to a process for rapidly charging uncharged toner particles to a positive polarity, which comprises adding uncharged toner particles to a positively charged developer composition comprising carrier particles and toner particles, the charged and uncharged toner particles containing conductive particles or conductive patches on their surface, which conductive patches are of a higher positive triboelectric charge than the toner polymer, contacting the charged toner particles with the uncharged toner particles causing positive charges to be transferred from the conductive particles on the charged toner particles, to conductive particles on the uncharged toner particles, within a period of from about 5 seconds to about 2 minutes, thereby resulting in substantially the same level of positive charge intensity for both the original charged toner particles and the added toner particles, such charge intensity ranging from about 5 microcoulombs per gram to about 50 microcoulombs per gram.
    • 本发明涉及将不带电荷的调色剂颗粒快速地充电到正极性的方法,该方法包括将不带电荷的调色剂颗粒添加到包含载体颗粒和调色剂颗粒的带正电荷的显影剂组合物中,所述带电和不带电荷的调色剂颗粒在其上包含导电颗粒或导电贴片 表面,哪些导电贴片具有比调色剂聚合物更高的正摩擦电荷,使带电的调色剂颗粒与不带电的调色剂颗粒接触,导致正电荷从带电的调色剂颗粒上的导电颗粒转移到未充电的调色剂上的导电颗粒 颗粒,在约5秒至约2分钟的时间内,从而导致原始带电的调色剂颗粒和所添加的调色剂颗粒的正电荷强度基本相同的水平,这种电荷强度范围为约5微克/克至 约50 microcou 克/克。

    • An apparatus for applying an electrical charge to a charge retentive surface by transporting ions through an ionically conductive liquid and transferring the ions to the member to be charged across the liquid/charge retentive surface interface. The ionically conductive liquid is contacted with the charge retentive surface for depositing ions onto the charge retentive surface via a wetted donor blade supported within a mechanically sealable housing adapted to permit movement of the wetted donor blade from an operative position in contact with the charge retentive surface, to a nonoperative position stored within the housing to prevent loss of the ionically conductive liquid in its liquid or vapor form so as to extend the functional life of the apparatus. In one specific embodiment, a wiper blade may be provided for removing any liquid droplets from the surface of the photoreceptor as may have been transferred at the donor blade/charge retentive surface interface.
    • 一种用于通过将离子传送通过离子导电液体并将离子转移到待充电的构件穿过液体/电荷保持性表面界面而将电荷施加到电荷保持性表面的装置。 离子导电液体与电荷保持性表面接触,用于通过支撑在可机械密封的壳体内的润湿的供体叶片将离子沉积到电荷保持性表面上,其适于允许润湿的供体叶片从与电荷保持性表面接触的操作位置移动 到存储在壳体内的非操作位置以防止其液体或蒸气形式的离子导电液体的损失,从而延长设备的功能寿命。 在一个具体实施例中,可以设置擦拭器刮片以用于从受光器的表面去除任何液滴,如可能在施主刀片/电荷保持表面界面处传送的那样。
