A stable and accurate numerical simulation technique is proposed to investigate performances of the transfer system using a biased transfer roller (BTR) in electrophotography copier and printer. A one dimensional layer-structured model was used to calculate steady state distribution of electric field and current under gas discharge. Based on the discharge current, concentration of generated ozone was also calculated. As results of calculations using parameters based on a typical black and white laser printer, it was shown that (1) a transfer system using a semiconductive BTR under constant current operation was robust against variation of paper resistance due to changes in the environment and materials, (2) concentration of ozone in the BTR system was two orders lower than that in the system using a conventional corona device.
