Abstract
The present invention provides an image display apparatus including an image bearing web in the form of an endless belt on which an erasable image is formed, the image being carried into an image display section for observation. If the image bearing web is photosensitive, it is affected by the light, resulting in the deterioration of the image formed. To avoid this, the length of the image bearing web which is used to form one complete image is made equal to the full length thereof divided by an integer. Therefore, that position on the image bearing web which is used to form an image to be displayed is not changed for each display to limit the portions of the photosensitive web exposed to light to predetermined areas, thereby avoiding the occurrence of the difference in image quality within each of the predetermined areas.
