検討されている。(Prior art and its problems) Since electrophotography was invented by Karlsson in 1938, it has been widely used in copying machines and printers.
It has become an essential piece of equipment in today's offices. Various types of photoreceptors have been developed, which can be called the heart of the photoreceptor used for this purpose. There are materials, etc.
Recently, photoreceptors made of amorphous silicon (a-5i) have also been considered.

与える。Among the characteristics required of such a photoreceptor, reliability for obtaining stable image quality over a long period of time is the most important. A factor that hinders this reliability is the rise in temperature of the photoreceptor during continuous use. Amorphous silicon has particularly unstable electrical properties, and the temperature of the photoreceptor increases (60
(up to about 70°C), which has an unfavorable effect on image quality.
