摘要： An electrostatic information recording medium according to this invention includes an inorganic oxide layer 3 and a photoconductive layer comprising a charge-generating layer 4 and a charge-transport layer 5 laminated onto an electrode 2 in this sequence, as illustrated in FIG. 1. To record information, the information is exposed to light while voltage is being applied between the electrode 3 and another opposite electrode, or alternatively voltage is applied therebetween while the information is being exposed to light.After information recording, the electrostatic information recording medium is uniformly electrified on its surface as by corona charging, whereby the information can be easily reproduced in the form of electrostatic information. This recording medium, if tone-developed, can be used as an original plate for electrostatic printing.

摘要： The present invention relates to an electrostatic information recording medium in which a charge retaining layer having high insulating properties is laminated on an electrode, and an electrostatic information recording/reproducing process wherein, while said electrostatic information recording medium is positioned in opposition to a photosensitive member on which a photoconductive layer is laminated, the recording medium is subjected to information exposure with the application of voltage between both electrodes to accumulate electrostatic charges thereon depending upon the dosage of said information exposure, and the electrostatic information thus accumulated is reproduced by potential reading. The present electrostatic information recording medium has an information density as expressed in terms of a high recording capacity of the order of 8.times.10.sup.8 bits/cm.sup.2, and makes it possible to process information in a planar state so that analog or digital information such as characters, line pictures, images, (0.multidot.1) information and sounds can be accumulated in the form of electrostatic charges. With the present electrostatic information recording medium, it is possible to obtain information of high quality and resolving power because of the information being accumulatable in electrostatic charge units. Due to its high charge retainability, it is further possible to store information permanently. Still further, it is possible to make inexpensive and simple recording/reproducing systems, since information can be output by reading local potentials of electrostatic latent images at any time and any scanning density.

摘要： An electrode 2c and a pinene polymer recording layer 2a with a molecular weight of 500 to 10000 are successively stacked on a substrate 2c, as shown in FIG. 3. By carrying out thermal development, information electric charge that is formed on the resin surface is formed into a thermally stable frost image without decay of the information electric charge. Since no photoconductive layer is needed, when transmitted or reflected light is used to reproduce the frost image, there is no effect of the coloring of a photo-conductive layer. If exposure is effected under the application of a voltage, since the depth of dimple patterns of a frost image varies in accordance with the quantity of exposure energy, tonal reproducibility is obtained. In addition, it is possible to obtain high resolution and make an original for OHP, a microfilm, a slidefilm, etc. which is of good quality and has high fidelty to the original document.

摘要： The present invention provides an electrostatic information-recording medium including an electrode layer (13) and a charge-retaining layer, in which said charge-retaining layer is formed of a laminate of a resin layer (11a) having a low glass transition temperature with a heat-resistant, insulating layer (11b), or an electrostatic information-recording medium comprising at least an electrode layer (13) and a charge-retaining layer (11) in which said charge-retaining layer (11) is formed of a polymer layer (12) containing pentafluorostyrene as a monomer component and having a weight-average molecular weight of 10,000 to 2,000,000, or which includes a photoconductive layer (44) and a charge-retaining layer (43) between a pair of electrodes (42) and (45) and is designed to carry out exposure with the application of voltage between both said electrodes (42) and (45) or apply voltage between both said electrodes (42) and (45) while exposure is carried out, thereby forming an electrostatic latent image, which is then carried on said charge-regaining layer (43) by releasing said charge-retaining layer (43) from said electrode 42, or which includes a charge transport layer (51) on an electrode (52) and is designed to record information on the surface of said charge-transport layer (51) by toner development and then apply electrostatic charges on the surface of said charge transport layer (51) to inject said electrostatic charges into said charge-transport layer through an electrically conductive layer of the toner, thereby forming electrostatic information corresponding to the toner information on said charge transport layer. Thus, the electrostatic information-recording medium can thus be improved in terms of the capability to retain electrostatic information. The electrostatic information retained in this electrostatic information-recording medium is very stable because of being accumulated in the charge-carrying layer. Also, the information can be easily reproduced in the form of information of high quality and resolution by detecting a potential difference between the electrode and the surface potential.

摘要： 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.
