摘要： An electrographic printing apparatus (10) has a charge retaining member (42) with a relatively high background potential of a first polarity, and a transfer corotron (50) having a relatively high potential of a second polarity providing a transfer region (48) for a transfer of toner to copy sheets (70). A pretransfer baffle (52) disposed adjacent to the transfer corotron to prevent image degradation, especially the halo effect. The pretransfer baffle is charged to a potential approximately the same as the charge retaining member and with the same polarity. A gap is present between the pretransfer baffle and the charge retaining member for the passage of copy sheets to the transfer region, and the copy sheet is brought into contact with the charge retaining member before reaching the transfer region. Preferably the copy sheets are conveyed to the baffle at a relatively large angle, e.g. between 30° and 80°, with respect to the charge retaining member.
摘要翻译：电子照相打印设备（10）具有电荷保持部件（42），具有第一极性的相对较高的背景电位;以及具有第二极性的相对较高电位的转移电晕（50），其提供转移区域（48）将调色剂转印到复印纸（70）。设置在转印科罗拉多附近的预转印挡板（52），以防止图像劣化，特别是光晕效应。将预转印挡板充电到与电荷保持部件大致相同的电位并具有相同的极性。在转印挡板和电荷保持构件之间存在用于使复印纸传送到转印区域的间隙，并且在到达转印区域之前使复印纸与电荷保持构件接触。优选地，复印纸以相对大的角度被传送到挡板，例如，相对于电荷保持部件为30°〜80°。

摘要： An ionographic imaging member containing a conductive layer (67) and a uniform and continuous dielectric imaging layer (66) free of voids, the imaging layer having a dielectric constant of from about 1.5 to about 40 and a thickness of at least about 45 micrometers, the thickness divided by the dielectric constant having a value of from about 30 to about 60 micrometers. This member may be used in an ionographic imaging process.
