Abstract This invention relates to a method for recording a visible image by forming an electrostatic charge image or an electric field image on a photoconductive insulating layer or a dielectric layer which is disposed on a substrate or a dielectric sheet or film and connecting said electrostatic charge image or said electric field image to said visible image by contacting said electrostatic charge image or said electric field image with an electroconductive toner sprinkled on said photoconductive insulating layer or said dielectric layer or said dielectric sheet or film, thereby to form said visible image, and fixing said visible image on said photographic insulating layer or said dielectric layer or said dielectric sheet or film under heating or in the presence of a solvent vapor.
A method for recording a visible image, according to claim 1, wherein the step for converting the electrostatic charge image or the electric field image to said visible image is carried out by contacting a plate or drum having concave cells in which the electroconductive toner is fed, with the surface of the fresh dielectric layer having the transferred electrostatic charge image or the transparent dielectric sheet having the electric field image.
Claim 2
Dependent Claim
70 words
A method for recording the visible image according to claim 1, wherein the step for converting the electrostatic charge image or the electric field image to said visible image is carried out by cascading or flowing a mixture of the electroconductive toner and electroconductive coarse granules over the surface of the fresh dielectric layer having the transferred electrostatic charge image or the transparent dielectric sheet having the electric field image.
Claim 3
Dependent Claim
