ABSTRACT:
An image recording apparatus with a photosensitive unit 100A which is rotatably structured, having a transparent conductive layer 2, a photoconductive layer 3, and a porous insulating screen 4 with an electrode layer 5 on its top surface which are sequentially stacked on a transparent substrate. 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.
