Title:
静電潜像再生方法
Document Type and Number:
Japanese Patent JP3512201
Kind Code:
B2
Abstract:
PCT No. PCT/JP92/00615 Sec. 371 Date Mar. 8, 1993 Sec. 102(e) Date Mar. 8, 1993 PCT Filed May 14, 1992.A charge carrier medium 1 including an insulating layer 11 laminated on an electrically conductive layer 12 with an electrostatic latent image 2 recorded on the insulating layer 11 is brought into contact with water, etc., to resurrect the attenuated potential. Alternatively, the charge carrier medium 1 is previously immersed in water, etc., to deposit onto the surface thereof charges opposite in polarity to those of the electrostatic latent image 2 generated by charging, thereby attenuating the surface potential. This makes any external access to the image information impossible. In reading the image information, a PET film 5 or the like is brought into close contact with the surface of the charge carrier medium 1, and is then peeled apart from that surface to remove the charges of the opposite polarity and thereby resurrect the image information for reading. This makes it possible to protect the image information against a third person's access thereto and provide an assured reproduction of the electrostatic latent image.
