ては不適当である。For example, the currently widely used selenium photoreceptor has difficult manufacturing conditions, is expensive, has no flexibility, and is difficult to process into a belt shape, and is sensitive to heat and mechanical shock. Therefore, care must be taken when handling it. Zinc oxide photoreceptors are low in cost because they can be manufactured by applying inexpensive zinc oxide to a support, but they generally have low sensitivity), surface smoothness/hardness, tensile strength, and durability. It has mechanical drawbacks such as friction, and there are many problems with durability as a photoreceptor for plain paper copying machines, which are usually used repeatedly. Furthermore, a photoreceptor using a charge transfer complex of TNF and PVK has low sensitivity and is unsuitable as a photoreceptor for high-speed copying machines.

がある。In recent years, extensive research has been carried out to eliminate the drawbacks of these photoreceptors, and in particular, various organic photoreceptors have been proposed. Among them, a laminated photoreceptor in which a thin film of an organic pigment is formed on a conductive support (charge generation layer), and a layer mainly composed of a charge transport substance (charge transport layer) is formed on this layer, which is different from conventional organic-based photoreceptors. Compared to photoconductors, they generally have higher sensitivity and stable chargeability, so they have attracted attention as photoconductors for plain paper copying machines, and some of them are in practical use.
