In recent years, the photocopier has been asked for high picture quality especially in the product printing market and needed to perform high control performance against the various process variation factors. It is important to control the amount of toner on the transfer medium precisely. In this paper,we propose to design a control system for the amount of toner using the model predictive control (MPC) based on the identified model. We show the result of comparison between the conventional control system and the proposed system. Especially we evaluate the control performance using the experiment data which was acquired by the test photocopier.
