Analysis for electrophotographic process on digital copier

To develop the most efficient electrophotographic system, a numerical analysis method, which estimates the output image on the paper, is developed. This method is based on the numerical analysis method, which calculates the field distribution in each process using fundamental measurement data. This method is applied to an electrophotographic system for digital copier, and numerical results of gamma characteristics and line width are confirmed with measured ones. This developed method enables us to optimize design parameters taking into account each process.
