    摘要: 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.

    摘要: A drive roller is rotated and a high voltage periodically alternating between plus and minus based on the potential of a conductive portion of the drive roller 2 is applied by a high voltage power source 4 to an electric charger, so that the surface of the drive roller 2 is charged plus and minus alternately. Since the drive roller 2 is charged, a sleeve 1 is absorbed to and held by the drive roller 2 so as to be rotated and fed together with the drive roller. Moreover, the sleeve 1 is separated from the drive roller 2 by a separator so as to obtain a sag. When the drive roller rotates further, the sleeve 1 is again absorbed to and held by the drive roller 2 charged periodically plus and minus, so as to be rotated together with the drive roller. Thus, the present invention eliminates scratches which may be caused by friction on a developing roller or on a photosensitive body surface and also eliminates contamination with oil.

    摘要: An image recording apparatus and an image recording method enable high density and without blank space between pixels printed on a recording medium to be printed. The image recording apparatus comprises a multi-hole photoreceptor provided with a transparent conductive layer, photoconductive layer, and multi-hole layer having a plurality of holes arranged with equal interval, on a transparent supporting structure, and an opposite electrode arranged so as to be opposite to the multi-hole photoreceptor with interval while inserting a recording medium. Conductive colored particles which fly in order from a plurality of holes of the multi-hole photoreceptor form respective pixels by driving the multi-hole photoreceptor corresponding to the pixel.
