摘要： A magnetic brush developer apparatus including a plurality of developer housings each including a plurality of magnetic brush rolls associated therewith. Conductive magnetic brush (CMB) developer is provided in each of the developer housings. The CMB developer is used to develop electronically formed images. The physical properties such as conductivity, toner concentration and toner charge level of the CMB developers are such that density fine lines are satisfactorily developed notwithstanding the presence of relatively high cleaning fields.

摘要： Printing apparatus for forming toner images in black and at least one highlighting color in a single pass of a change retentive imaging surface through the processing areas, including a development station, of the printing apparatus. The development station includes a pair of developer housings each of which has supported therein a pair of magnetic brush development rolls which are electrically biased to provide electrostatic development and cleaning fields between the charge retentive surface and the developer rolls. The rolls are biased such that the development fields between the first rolls in each housing and the charge retentive surface are greater than those between the charge retentive surface and the second rolls and such that the cleaning fields between the second rolls in each housing and the charge retentive surface are greater than those between the charge retentive surface and the first rolls.

摘要： Balanced, efficient corona transfer for both the charged area image and the discharged area image of a developed tri-level image is obtained by the provision of a selective pre-transfer charge corona device in combination with a pre-transfer discharge lamp. While improved transfer over prior art devices is obtained using a pre-transfer lamp prior to pre-transfer charging the preferred embodiment of the invention utilizes a pre-transfer lamp before and in coincidence with pre-transfer charging.

摘要： Tri-Level Highlight color imaging apparatus and cleaner apparatus therefor. Improved cleaning of a charge retentive surface is accomplished through matching the triboelectric properties of the positive and negative toners and their associated carriers as well as the carrier used in the magnetic brush cleaner apparatus. The carrier in the cleaner upon interaction with the two toners causes them to charge to the same polarity. The carrier used in the cleaner is identical to the one use in the positive developer. The carrier of the negative developer was chosen so that the toner mixed therewith charged negatively in the developer housing.Thus, the combination of toners and carriers is such that one of the toners charges positively against both carriers and the other of the toners charges negatively against one of the carriers and positively against the other. Due to the application of a positive pretransfer corona both the toners are positive when they reach the cleaner housing and because the carrier employed causes both of the toners to charge positively, toner polarity reversal is precluded.
摘要翻译：三层高亮度彩色成像设备及其清洁设备。充电保持性表面的改进的清洁是通过匹配正和负色调剂及其相关载体的摩擦电性质以及在磁刷清洁器装置中使用的载体来实现的。与两个调色剂相互作用时，清洁剂中的载体使它们以相同的极性充电。清洁剂中使用的载体与正极显影剂中使用的载体相同。选择负极显影剂的载体，使得与其混合的调色剂在显影剂外壳中呈负电荷。因此，调色剂和载体的组合使得其中一种调色剂对两种载体均具有积极作用，而另一种调色剂对载体之一产生负面影响并且与另一种载体正相反。由于使用了正面的预转印电晕，所以当调色剂到达清洁器壳体时，调色剂是正的，并且由于使用的载体导致两种调色剂均正向充电，否则调色剂极性反转被排除。

摘要： A magnetic brush developer apparatus comprising a plurality of developer housings each including a plurality of magnetic rolls associated therewith. The magnetic rolls disposed in a second developer housing are constructed such that the radial component of the magnetic force field produces a magnetically free development zone intermediate a charge retentive surface and the magnetic rolls. The developer is moved through the zone magnetically unconstrained and, therefore, subjects the image developed by the first developer housing to minimal disturbance. Also, the developer is transported from one magnetic roll to the next. This apparatus provides an efficient means for developing the complimentary half of a tri-level latent image while at the same time allowing the already developed first half to pass through the second housing with minimum image disturbance.

摘要： Undesirable transient development conditions that occur during start-up and shut-down in a tri-level xerographic systemw when the developer biases are either actuated or de-actuated are obviated by using a control strategy that relies on the exposure system to generate a spatial voltage ramp on the photoreceptor during machine start-up and shut-down. Furthermore, the development systems' bias supplies are programmed so that their bias voltages follow the photoreceptor voltage ramp at some predetermined offset voltage. This offset is chosen so that the cleaning field between any development roll and the photoreceptor is always within reasonable limits. As an alternative to synchronizing the exposure and developing characteristics, the charging of the photoreceptor can be varied in accordance with the change of developer bias voltage.
摘要翻译：通过使用依赖于曝光系统产生空间电压的控制策略来消除在三级静电复印系统中的启动和关闭期间发生的不期望的瞬态发展条件，当显影剂偏压被启动或去激活时，在机器起动和停机期间，光感受器上的斜坡。此外，开发系统的偏置电源被编程，使得它们的偏置电压在某个预定的偏移电压下跟随感光体电压斜坡。选择该偏移使得任何显影辊和感光体之间的清洁场总是在合理的限度内。作为同步曝光和显影特性的替代方案，可以根据显影剂偏压的变化来改变感光体的充电。

摘要： Full color, single pass and two-pass imaging processes using black, magenta, cyan and yellow toners and Non-interactive Development without fringe field development. Corona discharge is utilized for voltage leveling certain developed images prior to their passage through DAD developer housings. A Raster Output Scanner (ROS) used for creating the latent electrostatic images is also used for voltage leveling of images developed on the first pass of the two pass imaging process in order to remove certain other images for eliminating fringe field images as well as other undesired images.

摘要： A hybrid development system for developing composite tri-level xerographic latent images in which conductive magnetic brush (CMB) development system is employed at the first development station and insulative magnetic brush (IMB) development system is used at the second station. In order to preclude spurious fringe field development by the IMB development system at the second development station the conductivity of the IMB developer is in the order of 10.sup.-13 to 10.sup.-15 ohm-cm. Additionally, a scorotron corona charging device located between the two development housings may be used to charge the image developed at the first station to the same potential as the background (white level) thereby eliminating spurious fringe field development by the IMB developer with a conductivity less than 10.sup.-13 ohm-cm at the second development station.
