" J# F2 `. D4 q7 e( z
Recent technical progress in the area of office imaging equipment has made possible remarkable performance advancements in plain paper copiers, laser printers and facsimile machines. Improved properties of print imaging, speed, maintenance-free operation and low cost are especially required in today's demanding business environment. Critical to these imaging devices are static dissipative charger and developer rollers.

0 s  f( N, X% R) D+ r* \( _; |Charger rollers, responsible for depositing a uniform electrical charge across the surface of the photoconductive drum, must do so consistently across the surface of the roll to prevent copy shadow or type recurrence.

Developer rollers, responsible for transferring toner from the toner cartridge to the paper, must also have extremely consistent static electrical properties throughout the roller in order to achieve the highest possible print quality.

/ _, D. t9 u  ]$ ^9 L1 AHistorically, manufacturers of charger and developer rollers have had two design venues from which to choose. The first is a multilayer design concept where a conductive roll is surface treated with a static dissipative agent. Disadvantages with this design approach are with the inherent tendency for the agent to wear off with time and increased costs associated with the manufacture of multilayer rolls. The second is via addition of either conductive or nonconductive fillers (dependent upon the electrical properties of the base elastomer) into the final roller compound as method to achieve the desired static dissipative properties. The main concern with this type design approach is with inconsistencies in filler dispersion resulting in widely varying electrical properties across the surface of the roll.

Hydrin epichlorohydrin (ECO) elastomers that contain ethylene-oxide (EO) are naturally static dissipative and offer both technical and costs advantages in not requiring the addition of specialized fillers or coatings to achieve desired static dissipative properties. The electrical properties of Hydrin (ECO) are made more and more static dissipative by increasing its ethylene-oxide content. The wide variety of grades currently offered by the Hydrin ECO elastomer product line covers the full range of the static dissipative spectrum utilized by the imaging roller industry today.

Information included in this bulletin provides details concerning the static dissipative properties of Hydrin epichlorohydrin products in both raw polymer gum stock and filled compounds. Additional data on a variety of cure systems is also presented to illustrate their effect on the electrical properties.

! _% S/ K4 v) N. c1 h' m/ D5 k近年来，办公成像设备领域的技术发展，使得普通纸复印机，激光打印机和传真机在性能上有了显著提高。在当今的商业需求环境中，对提高打印影像质量，打印速度，以及设备免维护和低成本方面，都提出了特别的要求。成像设备的关键部件是静电耗散型充电辊和显影辊。

充电辊，作用是使光电鼓表面冲上均匀电荷；整个充电辊在使用过程中必须充电均匀、性能稳定，以防止发生底灰或重影，图象失真。

显影辊，作用是吸附碳粉将其从粉盒运送到打印纸上，显影辊工作时必须要使其表面具有均匀静电电荷特性，导电率保持均匀，以最大可能保证打印质量。

长期以来，生产商们一直使用以下2种设计方案来生产充电辊和显影辊。第一种是多层设计概念，将导电辊的表层使用一种静电耗散材料进行表面处理。这种设计方案的缺点是静电耗散材料所固有的降解性（随着时间），以及当今多层辊体日益增长的生产成本。第二种是通过向辊体中添加导电填料或非导电填料（取决于弹性体的导电性），以获得所需要的静电耗散特性。这种设计方法的核心是通过填料分散体中的导电和非导电材料，使辊体表面的导电性发生很大变化。
