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： An image forming apparatus of the present invention includes a particle conveying body made up of a light-transmitting conductive layer, an insulative'screen provided on the conductive layer and formed with a number of pores, and a screen electrode formed on the screen. Photoconductive, colored particles are charged to negative polarity and then caused to fill the pores by an electric field. When the particles in the pores are exposed via the conductive layer, electron-hole pairs are generated in the particles. An electric field of as high as 104 V/cm or above is formed between the conductive layer and the screen electrode and separates the electrons and holes. The electrons leak to the conductive layer and cause the particles to be charged to positive polarity. An electric field formed between a facing electrode positioned behind a recording medium and the conductive layer causes the particles to fly toward and deposit on the medium.

摘要： A liquid electrophotographic developing apparatus capable of preventing image drift and reducing the load in the squeezing process. A developing roller faces a photoreceptor belt with a predetermined spacing to supply a liquid developer to the photoreceptor belt while rotating at a peripheral velocity in the opposite direction to that of the photoreceptor belt in a developing region thereon. A peripheral velocity ratio of the peripheral velocity to a moving velocity of the photoreceptor belt is determined so as to maximize a solid component ratio of a developed toner layer on the photoreceptor belt.

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.

An electric field is applied between the transparent conductive layer 2 and the electrode layer 5. Therefore, when a light is irradiated to the photoconductive layer 3 via the transparent layer 2, a photoconductive phenomenon takes place. The electrode layer 5 has a potential so that the conductive particles returns to an electrode member 11. The electrode member 11 for holding conductive color particles on its surface is opposite to the photosensitive unit 100A with a gap between. The conductive particles filled between the porous insulating screen 4 are transferred to a record medium.
