In the copy machines or printers which adopt the electro-photographic system,toner particles are electrically charged, developed, then images are formed on the medium such as paper. It is very important to accurately measure the amount of charge. In order to improve the technology of electro-photography, parameter design was conducted on a blow-off charge measurement system. As a result, the amount of toner particle charge could be measured with a very good accuracy.
