Simulation of Two-Component Development Process for Frontloading Design
Abstract:This report describes simulation technologies for digital frontloading of two-component development process in electrophotography. Electrophotography entails using multiphysics involving phenomena with yet unclear mechanisms such as air breakdown, tribocharging and powder dynamics. Thus, it requires much effort and many resources to develop electrophotography products. Numerical simulation is widely recognized as one of valid approaches to overcome these difficulties in product design. A tool for simulating the two-component development process has been developed including particle motion calculation using the Distinct Element Method and electric filed calculation using the Finite Element Method. The tool working on PC clusters is equipped with force decomposition method as a high-efficiency parallel computation algorithm to reduce calculation time. In addition, GUIs, and an online portal for PC clusters has been developed to support product designers utilizing the simulation tool. Validity of the tool was confirmed by comparison of developed toner mass and developer mass on development roller with the experimental results.
