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.

摘要： A reversible image display medium accommodates a dry developer in each cell formed between two substrates. The developer contains at least two kinds of frictionally chargeable dry developing particles having different chargeable polarities and different optical reflection densities. An image display can be achieved by forming an electrostatic latent image on one of the substrates to drive the developing particles in an electric field based on the electrostatic latent image. The developing particles are set to an average charge quantity of 1.0 &mgr;C/g to 10 &mgr;C/g to achieve good image display. Optionally at least one kind of the developing particles are magnetic developing particles having a coercive force of 50 oersteds to 250 oersteds, and optionally having an optical reflection density of 1.0 or more. An amount of small-size developing particles and/or an addition of a third component may be adjusted and volume average particle size ratio of developing particles may be controlled.

The sheet has an irregular surface including a plurality of concavities in the form of continuous grooves for receiving the toner and ridges extending along the concavities, and a toner image can be formed by removably adhering the toner to the concavities. The ridges of the irregular surface are capable of protecting the toner adhering to the concavities. The continuously grooved concavities have a depth (height of ridges) of 20 μm to 150 μm; and a condition of E·A≧2 [GPa·μm] can be established wherein E[GPa] means Young's modulus and A [μm] means a width of ridges, the Young's modulus being a value when a material for forming the concavities and ridges is elongated by 1%. The ridges may be reinforced by reinforcing portions for retaining postures of the ridges.
