Electrophoretic printing method and electrophoretic printer
First Claim
1. An electrophoretic printing method comprising:
- layering a back electrode and a dispersion system containing electrophoretic particles on a printing substrate to form a printing layer; and
providing a printing head separately from the printing substrate, the printing head having a front electrode which is a counterpart of the back electrode and which has a predetermined printing pattern;
wherein the front electrode is brought into contact with the printing layer formed on the printing substrate to oppose the back electrode, and voltage is applied between the front electrode and the back electrode so as to change a distribution of the electrophoretic particles according to the polarity of the voltage and to form a desired image on the dispersion system.

Abstract
An electrophoretic printing method comprises layering a back electrode and a dispersion system containing electrophoretic particles on a printing substrate to form a printing layer; and providing a printing head separately from the printing substrate. The printing head has a front electrode which is a counterpart of the back electrode and which has a predetermined printing pattern. The front electrode is brought into contact with the printing layer formed on the printing substrate to oppose the back electrode. Voltage is applied between the front electrode and the back electrode so as to change a distribution of the electrophoretic particles according to the polarity of the voltage and to form a desired image on the dispersion system.
