のが普通である。[0003] Further, an electrode is deposited on the photoconductive layer, the entire surface of the photoconductive layer is charged by corona charging in a dark place, and then exposed to strong light to make the photoconductive layer exposed to light conductive. By leaking and removing the charge at that portion, an electrostatic latent image is optically formed on the surface of the photoconductive layer, and a toner having a charge of the opposite polarity (or a charge of the same polarity) as the residual electrostatic charge is formed. There is an electrophotographic technology that attaches and develops it, but it is mainly used for copying, and generally cannot be used for photography due to low sensitivity, and electrostatic latent image formation due to short electrostatic charge retention time Usually, the toner is developed immediately thereafter.

通したような状態となることを見出した。The electrostatic information recording medium in which an inorganic oxide layer and a photoconductive layer are sequentially laminated on an electrode is opposed to a counter electrode, and information exposure is performed while applying a voltage between the electrodes.
