摘要： An apparatus for obtaining measurements of the charge on a surface of a member during a period of time while applying a charge to the surface of the member is provided. The apparatus includes a frame. The member is rotatably secured to the frame. The apparatus also includes a charging device for applying the charge to the member. The charging device includes a charging device portion thereof positioned proximate to an external periphery of the member. The apparatus also includes a mechanism for rotating the member. The mechanism is operably associated with the frame. The apparatus also includes a charge measuring device operably associated with the support for measuring an electrical field emanating from the member. The charge measuring device includes a measuring device portion thereof positioned proximate to a measured position on an external periphery of the member. The mechanism is cooperable with the member to rotate the member. The charge measuring device is adapted to measure a charge at the measured position after the member is so rotated.

摘要： A system for conditioning liquid ink made up of toner particles immersed in a liquid carrier medium being delivered to or on an image bearing surface in a multicolor electrostatographic printing machine of the type utilizing liquid developing material, particularly an image-on-image type liquid ink multicolor system. The liquid ink conditioning system includes a first member for electrostatically compressing or compacting the toner particles towards or on the image bearing surface. A second member is provided downstream from the first member for removing excess liquid from the compressed liquid ink layer. The present invention allows for a high magnitude electric potential to be applied to the first member for generating a large electric field to electrostatically compress toner particles towards or on the image bearing surface while a second member accomplishes excess liquid material removal from the liquid ink having a compressed toner layer, thereby avoiding image distortion that may accompany prior art devices which attempt to accomplish both image compaction and excess liquid removal in a single device.
