も不便であるなどの欠点を有している。 Conventional recording methods using electrostatic charges include electrophotography, which uses a photoconductive material to form an electrostatic latent image through charging and exposure, and electrostatic, which forms an electrostatic latent image by directly charging a dielectric layer. The recording method is known, and the formed electrostatic latent image is developed using a developer to obtain a developed image, which is then directly fixed, or this developed image is transferred to general paper etc. and then fixed and recorded. paper is obtained. However, directly fixed recording paper has drawbacks such as poor appearance and feel compared to ordinary paper, and is also inconvenient to handle.

にカブリを生じ、黒く汚れてくる欠点があつた。 Conventionally, surfactants, organic or inorganic salts, polymer electrolytes, fine metal powders, etc. have been known as conductive agents for electrostatic recording materials. Among these, surfactants, salts, and polymer electrolytes are Since the resistance value changes greatly depending on the amount of water contained, the recording characteristics are influenced by humidity. Furthermore, when metal powder is used, the resistance value changes little due to humidity, but the resistance value changes greatly depending on the slight difference in the amount of compounding or the coating method, so it is difficult to create something with constant recording characteristics. It was hot. In addition, as highly insulating resins that form the dielectric layer, vinyl acetate resin, vinyl chloride resin, silicone resin, epoxy resin, acrylic resin, vinyl acetate-crotonic acid copolymer, styrene-butadiene copolymer, chloride Vinyl-vinyl acetate copolymer, vinyl chloride-vinylidene chloride copolymer, etc. are known, but when these are used in electrostatic recording media that are used repeatedly, the cleaning properties deteriorate during use. The disadvantage was that the recording paper gradually became foggy and stained black.

However, if it exceeds 5 μm, it is undesirable because it causes abrasion of the recording needle, a decrease in transfer efficiency, and a decrease in cleaning properties for residual toner.
