Abstract
An image displaying apparatus, a method for displaying an image and an image displaying medium can provide an image of a large viewing angle and high stability of the particles upon repeated use. On electronic paper containing a display substrate formed of a hole transporting film, a non-display substrate formed of a film having a two-layer structure containing a charge transporting film having formed thereon an electrode layer having a thickness of about 50 .mu.m, and conductive black particles and insulating white particles contained therebetween, an electric field is generated at a position corresponding to image data by a recording head, so as to move the black particles attached to the entire surface of the display substrate toward the non-display substrate, whereby an image of contrast of black and white is formed on the display substrate.
