After forming an electrostatic latent image using toner and developing it with toner (colored powder or liquid developer), the toner is fixed by heat, pressure, drying, etc. to obtain a record.

力等に利用されている。[0003] Electrostatic recording media have excellent recording speed and recording storage properties, and also have excellent resolution due to the use of recording electrodes with a high resolution of 16 dots/mm. Further, as a large plotter for CAD, an electrostatic plotter has a faster recording speed than a pen plotter, and is suitable for outputting a large number of drawings. Furthermore, in recent years, color CAD plotters have been used not only to create blueprints for buildings, precision instruments, integrated circuits, and other objects, but also to produce aesthetic paintings, photographs, and other designs.
It is used for enlarging printed matter, outputting computer graphics, etc.

ター内の多くの部分に接触することとなる。In recording with an electrostatic plotter, a recording medium such as paper, cloth, film, etc. moves within the plotter from a paper feed section to an electrode section to a developing section to a cutter section to a paper distribution section. In the case of monochrome electrostatic recording, only development with black toner is required, and one pass of paper is sufficient. on the other hand,
In the case of color electrostatic recording, development is required four times for the three primary colors (cyan, magenta, yellow) and black.
In the multi-pass method, it is necessary to pass the paper four or more times. Even in the single-pass method, there are four sets of electrodes and developing sections, and the paper passing distance is long. The recording medium comes into contact with the platen roll, metal roll, and many other parts of the plotter not only from the recording surface of the dielectric layer but also from its back surface.

る。[0005] If paper or cloth has an appropriate thickness and stiffness, running defects will not occur. However, an electrostatic recording material based on an insulating material such as a resin film is charged with static electricity due to friction on its back surface, causing it to stick to the plotter and cause poor running.

カブリ等の不良画像を形成してしまう。Furthermore, during recording, when forming an electrostatic latent image, surplus charges generated in the conductive layer are dissipated in the thickness direction of the recording medium with a base material such as paper or cloth, and a good image is obtained. With an insulating base material, it is impossible for excess charge to dissipate in the thickness direction of the recording medium, and the excess charge dissipates in the width direction and flow direction, causing background fog that colors the blank area other than the recording area, and development. In some cases, a defective image such as leading fog, which is colored at the front part of the recording medium in the flow direction other than the recording part, is formed.

The edge conductive layer provided on the recording body is provided on one or both sides in the width direction of the recording body, but if it is provided on both sides, the shape of both edge conductive layers is the same as long as the back conductive layer and the conductive layer can be electrically connected. It may or may not be symmetrical, and any combination of shapes shown in FIGS. 1 to 5 may be used.

る。The reason why such a recording medium has good running properties and image quality is considered to be as follows. That is, the reason why the running properties are good is considered to be that the surface electrical resistance value of the back surface of the recording medium can be lowered by the conductive layer on the back surface, making it difficult for frictional charging to occur. In addition, the reason why fog is good and the recording density is increased is that the excess charge generated in the conductive layer during electrostatic latent image recording is transmitted to the back conductive layer via the edge conductive layer, and the plotter is in contact with the back surface of the recording medium. This is thought to be due to dissipation into metal parts.
