Abstract
Provided are an image display medium which satisfies a safety and a high-speed response and which is capable of repetitive rewriting, an image-forming method in which an image can be formed on the image display medium, an image-forming apparatus, and an initializer. In the image display medium, conductive particles and insulating particles are interposed between a display substrate and a non-display substrate having a positive charge-transporting property. An electrostatic latent image adapted to the image is formed on an electrostatic latent image carrier. A bias voltage is applied to a counter electrode. Positive charges (non-image portion) on the electrostatic latent image carrier are transferred to the display substrate to charge the conductive particles. The charged conductive particles are moved toward the non-display substrate. In the uncharged portion (image portion) of the electrostatic latent image carrier, positive charges are transferred to the non-display substrate from the counter electrode to charge the conductive particles. The charged conductive particles are moved toward the display substrate.
