Abstract
The transfer process of the color electro-photographic system consists of various parts, including a photoconductor drum, transfer roller, intermediate transfer belt, toner, paper, and saw-like static charge eliminator. Each of the components physically interacts with each other, creating electric fields with electric conduction, electric discharges, ion flows;thus, the components transfer the toner, and electrify and deform the paper. We have developed a simulator which considers multi-physics above to analyze physical phenomena occurring in the transfer process and also clarifies the latitudes appropriate for the robust design. The developed simulator was applied to calculate the current characteristics, electric discharges, toner scattering and paper transportation of the intermediate transfer system. The results of the simulator showed good agreement with the experiments. The developed simulator is useful for the analysis of the physical phenomenon mechanism and the estimate of various design latitudes.
