Abstract

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.

Dependent claims

An image recording method comprising the steps of:

(a) forming an electrostatic latent image corresponding to an image to be recorded on the surface of an electrostatic latent image forming material, said forming step comprising the steps of
(i) first uniformly neutralizing any charges on the electrostatic latent image forming material with a discharging corotron,
(ii) then uniformly charging the surface of the electrostatic latent image forming material with a charging corotron, and
(iii) then forming an electrostatic latent image on said surface through discharging by applying a voltage to a pin electrode in non-contact very close to the surface of the electrostatic latent image forming material,
(b) laying a recording material having a high resistance value and dielectric coefficient on said electrostatic latent image forming material,
(c) visualizing an electrostatic latent image on said recording material corresponding to the electrostatic latent image of said electrostatic latent image forming material by supplying developer to the surface of said recording material not facing said electrostatic latent image forming material,
(d) laying an ordinary recording paper on said recording material storing the visualized image,
(e) duplicating the visualized image formed on said recording material onto said ordinary recording paper by duplication means, and
(f) fixing the developer on said ordinary recording paper.
