ところが直接定着した記録紙は一般紙の場合と比
べてその外観や感触が悪く、またその取扱いも不
便であるなどの欠点を有している。 Conventionally, recording methods using electrostatic charges include electrophotography, which uses a photoconductive material and forms an electrostatic latent image through charging exposure, and electrostatic recording, which forms an electrostatic latent image by directly charging a dielectric layer. The method is well 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 to form a recording 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.

などの欠点のあるものが多かつた。 On the other hand, in the case of the transfer method, general paper is used as the recording paper, which eliminates the above drawbacks, but in this case, the recording medium is used repeatedly, so humidity changes during repeated use and the temperature inside the device increases. Many of them had drawbacks such as the recording characteristics of the recording medium deteriorated due to the increase in color, resulting in poor clarity, decreased density, and no gradation.

とは困難であつた。 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.
