System for decoding compressed data

A new image recording method, such as an electrophotographic method or electrostatic recording method, where a plurality of recording papers, each having visualized images, can be produced from an electrostatic latent image which is formed only once on the electrostatic latent image forming material. A recording material having a high resistance value and dielectric factor is laid on the electrostatic latent image forming material after an electrostatic latent image corresponding to a image to be recorded has been formed on said electrostatic latent image forming material. An electrostatic latent image on the recording material corresponding to the electrostatic latent image on the electrostatic latent image forming material is visualized by supplying developer to the surface of the recording material not facing or opposite to the electrostatic latent image forming material. Thereafter the developer on said recording material is fixed. In the same way, a recording paper having a plurality of the same image or recording papers with the same image can be produced as required by laying another recording material on the same electrostatic latent image forming material having the previously formed latent image and developing same.

Image recording method

An electrophotographic recording device suitable for a Form Overlay System, by which a latent image is formed on a surface of a light-sensitive recording medium, consisting of a first area which is maintained at an original potential, a second area which is maintained at a partially reduced potential and a third area which is maintained at a potential of zero.

Electrophotographic recording device

An electrostatic transfer process and apparatus for transferring an image comprised of letters, symbols and patterns onto a sheet of plain recording paper from an electrostatic latent image forming material comprised of a conductive substrate and an insulating layer formed on the substrate. The insulating layer surface of the electrostatic latent image forming material is uniformly charged with electrostatic charges. The charges of only image forming areas of the insulating layer surface are subsequently erased so that an electrostatic latent image is formed in the image forming areas. Thereafter, the electrostatic latent image forming material moves past a developing electrode to which is applied a voltage of the same polarity as that of the charges applied to the insulating layer of the electrostatic latent image forming material. Simultaneously, a developer having a charge of the same polarity as that of the voltage applied to the developing electrode is supplied to the image forming areas of the insulating layer surface to allow the developer to adhere to the area wherein the charges have been removed or diminished. Thus, the latent image is visualized. The resultant visualized image is transferred onto a sheet of plain paper for obtaining a clear recorded image.
