For example, when an organic electronic material is used as an electrophotographic photoreceptor, the organic photoreceptor is made of a material with charge generation ability (hereinafter referred to as charge generation material) and a material with charge transport ability (hereinafter referred to as charge generation material).
Hereinafter referred to as charge transport material. ) are used in combination, a charge generation layer and a charge transport layer are laminated together, or a charge generation material is dispersed in a charge transport material. The charges to be transported may be holes or electrons, but examples of charge transport materials with electron transport ability include polyvinylcarbasol (PVK). : ) Only a 1:1 mixture of 17 nitrofluorenone (TNF') has been used in practice, and most charge transport materials have hole transport properties such as pyrazoline and hydrazone. Conventional photoreceptors using charge transport materials with hole transport ability are
Because the substrate, charge generation layer, and charge transport layer are stacked in this order, the photoreceptor must be charged with negative polarity, which causes the photoreceptor to be chemically altered by negatively charged ozone. Unable to avoid the point, α-86
Alternatively, it has the drawback that printing durability is significantly lower than that of inorganic photoreceptors such as α-8i, and furthermore, it is not possible to obtain a photoreceptor that can be charged to both positive and negative polarities (ambipolar photoreceptor). It has the following drawbacks. It is desired to develop a photoreceptor that can be positively charged at these points, that can transport electrons, and that can be charged to both polarities.
