For example, when an organic electronic material is used as the electrophotographic photosensitive member, the organic photosensitive member has a material having charge generating ability (hereinafter referred to as charge generating material) and a material having charge transporting ability (hereinafter referred to as charge transporting material). Are used in combination, and are used by stacking a charge generation layer and a charge transport layer, or by forming a layer in which a charge generation material is dispersed in a charge transport material. Holes or electrons can be considered as the charge to be transported, but a 1: 1 mixture of polyvinylcarbazole (PVK) and trinitrofluorenone (TNF) can be put to practical use as a charge transport material having "electron transporting ability". Most of the "charge transport materials" are those having a hole transport property such as pyrazoline and hydrazone. A conventional photoreceptor using a charge transport material having a hole transporting ability has to be laminated in the order of a substrate, a charge generation layer and a charge transport layer, and therefore the photoreceptor must be charged with a negative polarity. Therefore, the problem that the photoreceptor is chemically deteriorated by the negatively charged ozone cannot be avoided, and the printing durability is remarkably higher than that of the inorganic photoreceptor such as α-Se or a-Si. It has a drawback that it is low, and further, it has a drawback that a photoreceptor capable of being charged in both positive and negative polarities (bipolar photoreceptor) cannot be obtained. From these points, positively chargeable, that is, electron transportable,
Furthermore, the advent of a photoconductor capable of being charged in both polarities is desired.
