    • A porous photosensitive unit has a transparent conductive layer formed on a surface of a transparent substrate. A photoconductive layer is formed on a surface of the transparent conductive layer. A porous insulating layer formed on a surface of the photoconductive layer has a plurality of holes for holding conductive color particles. The plurality of holes includes a first hole and the adjacent second and third holes. An upper or screen electrode is formed on a surface of the porous insulating layer except where the holes are formed. The photosensitive unit includes an optical arrangement in which, when a light source emits light to cause conductive color particles to fly out of the first hole only, the light exposes a region, within the photoconductive layer, which substantially coextends with a surface portion of the photoconductive layer that is exposed by the first hole.
