Abstract
The quality of an image recorded on electronic paper is improved. Specifically, electronic paper for displaying an image is supplied in a region in which an electric field is generated in the thickness direction of the electronic paper, the electronic paper having charged color particles and being used for displaying an image as a result of charged color particles migrating in the thickness direction. Voltage for generating an electric field in the region is controlled by a voltage control section so that the value of the voltage varies together with time. The quality of an image recorded on electronic paper can thereby be improved.
