The simulation methods for design of electrophotographic system are developed. A Simulation model of electrification behavior in flow of toner particles is proposed with taking the friction between the toner particle and the other materials into consideration. The simulation, model is able to apply the design of toner particles with optimal electrification property and the estimation of the charge distribution of toner particles flowing in the development system.The simulation of flowing behavior of toner particles in a one-component development system is performed to investigate the effects of the regulation methods on the formation of toner thin layer and the charge distribution of toner particles. This simulation of flowing and charging behavior of toner particles by particle element method is useful to design the one component development system.In order to clarify the development characteristics of 2-component magnetic brush development system in electrophotogtaphy, the flow behavior of developers was simulated by 3-dimensional particle element method. The magnetic brush of developers is expressed by taking into account the magnetic force between carrier particles. The development behavior of toner particles is simulated by taking into account the electric force, which is applied by the development bias voltage, to toner particles. This simulation method gives useful information on the optimal design of the development process.

提出了电子照相系统设计的仿真方法。考虑碳粉颗粒与其他材料之间的摩擦，建立了碳粉颗粒流动中的带电行为模拟模型。该仿真模型能够应用于设计具有最佳电气化性能的碳粉颗粒和估计在开发系统中流动的碳粉颗粒的电荷分布。通过对单组份显影系统中碳粉颗粒流动行为的模拟，研究了调节方法对碳粉薄层形成和碳粉颗粒电荷分布的影响。用粒子元法模拟了碳粉颗粒的流动和充电行为，为单件开发系统的设计提供了理论依据。为了明确二组分磁刷显影系统在电摄影中的显影特性，采用三维粒子元法对显影液的流动行为进行了模拟。显影剂的磁刷是通过考虑载体颗粒之间的磁力来表示的。通过考虑显影偏置电压对碳粉粒子施加的电场，模拟了碳粉粒子的显影行为。这种仿真方法为开发过程的优化设计提供了有用的信息。
