PROBLEM TO BE SOLVED: To improve the stability of transmittance in a translucent state in a light quantity adjusting apparatus for an imaging apparatus using an electrophoretic device. SOLUTION: A driving electrode for the electrophoretic particles formed on a transparent substrate is provided with a push electrode different from the driving electrode so as to eliminate charged particles nearby. Thus, the light transmitting state of the device is made according to the electrode pattern and voltage, whereby the fixed transmittance is accurately obtained. COPYRIGHT: (C)2004,JPO
