Abstract:
1. An image hold body comprising: a movable support body; a plurality of pixel electrodes (i) that is provided on the support body, (ii) that is arranged like a matrix in pixel units along a moving direction of the support body and a crossing direction crossing the move direction, and (iii) to which a latent image voltage is applied based on an image signal; charge storage members that are provided on the support body in a one-to-one correspondence with the pixel electrodes and that store charge corresponding to the latent image voltage applied to the pixel electrodes; switch members that are provided on the support body in a one-to-one correspondence with the pixel electrodes and that switch a timing of applying the latent image voltage to the pixel electrodes; scanning lines that are provided on the support body, and that select and scan a plurality of pixel electrode groups to be scanned through the switch members, the plurality of pixel electrode groups arranged in the crossing direction of the support body; signal lines that are provided on the support body and that apply the latent image voltage based on the image signal through the switch members to the pixel electrodes of each of the pixel electrode groups selected by the scanning lines in the pixel electrode groups arranged in the move direction of the support body; and shield members that are provided on the support body corresponding to the signal lines placed in the proximity of the pixel electrodes and that shield an effect of at least a part of an electric field from the signal line on an electric field based on the latent image voltage of the pixel electrodes, wherein the shield members are provided so as to shield all of the signal lines positioned between the pixel electrodes.
