Abstract
A recording medium includes a liquid crystal material whose polarizing axis is controlled by an applied electric field, a layer including the liquid crystal material, and spacers for maintaining a constant spacing between the layer, and is formed in the form of a sheet. A visible image is recorded on the recording medium by applying a predetermined electrostatic charge image composed of electrostatic charges on a surface thereof and by controlling the polarizing axis of the liquid crystal material by an electric field formed by the charges of the electrostatic charge image, which controls reflectance or transmittance of incident light.
