    摘要: There is provided a photoelectric conversion device for an electro-magnetic radiation beam incident thereto, into a charge pattern, the electro-magnetic radiation beam carrying information intended to be recorded. The device has electrodes, a photo-conductive layer member laminated to the electrodes having maximum thickness and a surface defining the maximum thickness between the electrodes, and a gap defined between the surface and a recording member disposed to face the surface of the photo-conductive layer member. There is further provided an apparatus for recording a charge latent image without losing the high resolution. The apparatus has a photoelectric conversion device having an electrode and a photo-conductive layer member on which the charge latent image is generated by projecting an optical image carrying information signals to the photo-conductive layer member, and a recording member having an electrode and a charge holding layer member facing the photo-conductive layer member to form a gap therebetween. A predetermined voltage is applied between the electrodes of the photoelectric conversion device and the recording member to transfer the charge latent image to the charge holding member by spark discharge.
