摘要： A method and apparatus capable of displaying a high-quality image using a reversible image display medium in which a cell(s) formed between two substrates accommodates at least two kinds of frictionally chargeable dry developing particles having different chargeable polarities and different optical reflection densities in image display, an electric field strength of, e.g., 0.3 V/μm to 3.0 V/μm is applied to the developer. An oscillating force (e.g. oscillating magnetic filed) is applicable and the oscillating force is substantially stopped during application of the electrostatic field. After completion of the electrostatic field, the surface of the medium on the image observation side may be charged to a potential holding the displayed image. Optionally, before image display, an alternating electric field may be applied to stir the developer for initialization of the medium.
