    • A development system which includes a flexible donor belt having groups of electrode array near the surface of the belt is disclosed. The Electrode array has group areas in which perform the function of: Loading; Transferring; Developing; Transferring and Unloading. Each electrode array group area is independently addressable and operatively connected to voltage source in order to supply a voltage in the order of .quadrature.0-1000 volts AC or DC to each group area. The electrodes array group area picks up the toner from the magnetic brush. An electrode array group area connected to the voltage source via phase shifting circuitry such that a traveling wave pattern is established. The electrostatic field forming the traveling wave pattern pushes the charged toner particles about the surface of the donor belt from the magnetic brush to the photoconductive belt where they are transferred to the latent electrostatic images on the belt by an electrode group area which generates a toner cloud in the development zone. Thereafter, toner is moved by an electrode array group area where an electrode group area is bias to unload remaining toner off the belt.
    • 公开了一种显影系统,其包括在带表面附近具有电极阵列组的柔性供体带。 电极阵列具有组合区域,其中执行以下功能:加载; 转让 发展; 转移和卸载 每个电极阵列组区域是可独立寻址的并且可操作地连接到电压源,以便向每个组区域提供大约为-1000伏交流或直流电压的电压。 电极阵列组区域从磁刷拾取调色剂。 电极阵列组区域,通过相移电路连接到电压源,使得建立行波模式。 形成行波图案的静电场将电荷调色剂颗粒从供电带的表面推压到感光带上,在这些带电调色剂颗粒通过产生调色剂云的电极组区域转移到带上的静电潜像上 在开发区。 此后,通过偏置电极组区域的电极阵列组区域移动调色剂,以将剩余的调色剂从带上卸下。
