    • An electrostatic recording body is constructed by laminating a glass substrate transmissive of recording light, a first conductive layer transmissive of recording light, a photoconductive layer exhibiting conductivity by receiving recording light, an insulating dielectric layer, and a second conductive layer transmissive of readout light, in this order. DC voltage is applied to the electrostatic recording body by a power source to charge both conductive layers, and an object is irradiated with light from a recording light irradiating means, thereby recording a electrostatic latent image at an interface between the photoconductive layer and the dielectric layer. Then, the conductive layers are short-circuited and charged at the same potential, thereby redistributing electrical charges. Exposure is performed by scanning with readout light from a readout exposure means, and current flowing out of the electrostatic recording body is detected by a current detecting means, thus reading out the electrostatic latent image.

    • The present invention provides an image-recording process wherein the voltage applied between a photosensitive member 2 and electrostatic information recording medium 1 is put off after the lapse of a given time from the closing of an exposure shutter 13. It is thus possible to move all the generated carriers onto electrostatic information recording medium 1 and accumulate them as charges in an amount corresponding to the quantity of exposure irrespective of a voltage shutter time. It is also possible to electrically charge electrostatic information recording medium 1 or the photosensitive member 2 in advance and put on-off an electrical connection between the electrodes of the photosensitive member 2 and electrostatic information recording medium 1 to control image exposure, thereby dispensing with any external high voltage power source and obtaining a positive image. In addition, it is possible to avoid the occurrence of inverse discharge and prevent the resulting image from falling into disorder by separating the photosensitive member 2 and electrostatic information recording medium 1 from each other, while voltage remains applied between the electrodes thereof, after an electrostatic image has been formed on the electrostatic information recording medium 1, and putting off the voltage impressed.

    • An x-ray imaging system for intraoral dental radiography. The imaging process is based on xeroradiographic principles, the surface of a small photoconductive plate being electrically charged. After insertion into a carrier, to form a light-tight cassette, the photoconductive plate is placed in a patient's mouth and x-ray exposed. The cassette, and the resultant electrostatic charge image therein, is inserted into the system processor, the photoconductive plate removed and transported to a developer station wherein the image is developed using liquid toner. The toner image is then dried and transferred from the photoconductive plate by using a transparent adhesive material and fixed to a white plastic substrate, forming an image carrier wherein the image can be viewed in reflectance or transmittance. After cleaning, the photoconductive plate is available for reuse. The system has a storage compartment for receiving cleaned photoconductive plates of various sizes for subsequent insertion into an empty cassette. An output station having a device for determining the size of the empty cassette mounted therein provides a control signal which permits a cleaned plate of a predetermined size to be fed into the empty cassette. The developed xeroradiographic images are exposed and processed sequentially, processing time being approximately 20 seconds, the developed images having the characteristics of edge enhancement and deletion, the xeroradiographic images therefor having advantages over film images.

    • A process for forming an electrode utilized in apparatus for minimizing the smear of an image produced by xeroradiography. A sheet comprising a thin layer of dielectric material sandwiched between two X-ray transparent electrically conductive surfaces is cut to the desired outside dimensions. A chemically resistant material is applied to both conductive surfaces in a predetermined pattern. The sheet is dipped into an etching bath removing material from the unmasked portions of the conductive surfaces and then dipped into a neutralizing solution to neutralize the etching chemical. The sheet is then rinsed, dried and the resistant material is removed. An adhesive material is coated on one of the conductive surfaces whereby the sheet, formed into the desired electrode, is affixed to the lid of a cassette utilized in the xeroradiography process
