Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrophotographic photoreceptor, and more particularly, to an electrophotographic photoreceptor excellent in photosensitivity, printing characteristics and repetition characteristics characterized by using a specific charge transport material in combination. About the body.

[0002]

2. Description of the Related Art Electrophotographic methods using the Carlson process and other various deformation processes are widely used in copiers and printers. Among the photoreceptors used in such an electrophotographic method, those using an organic photosensitive material have been used in recent years because of their advantages of low cost, mass productivity and no pollution. The mechanism of the formation of the electrostatic latent image on the photoconductor is as follows:
Light is absorbed by the charge generating material, and the charge generating material that has absorbed the light generates charge carriers, which are injected into the charge transporting material and charge transporting layers (or photosensitive layers) according to the electric field generated by the charging. It moves inside and neutralizes the charge on the photoreceptor surface to form an electrostatic latent image.

[0003] Organic electrophotographic photoreceptors include a photoconductive resin represented by polyvinyl carbazole (PVK), P
VK-TNF (2,4,7-trinitrofluorenone)
A charge-transfer complex type represented by, a pigment dispersion type represented by a phthalocyanine-binder, a function-separated type photoconductor using a combination of a charge-generating substance and a charge-transporting substance, and the like are known. Photoreceptors have attracted attention and have been put to practical use. Conventionally, various organic materials for photoreceptors have been developed. However, to make these electrophotographic photoreceptors that can be practically used, sensitivity, accepting potential, potential holding property, potential stability, residual potential, spectral Various characteristics are required, such as electrophotographic characteristics represented by characteristics, mechanical durability such as abrasion resistance, and chemical stability against heat, light, and discharge products. In particular, it is important that the material has high sensitivity and excellent repetition stability, but high sensitivity characteristics to some extent can be achieved by selecting an appropriate material. On the other hand, in addition to this, studies have been made on combining mechanical durability, but none of conventionally proposed organic photoreceptors satisfying all of the above conditions has been obtained. Therefore, an electrophotographic photoreceptor using conventionally proposed organic materials as conventional is not sufficient in terms of both high sensitivity and stability due to repeated use, and its completion has been eagerly desired. .

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide an electrophotographic photosensitive member which exhibits excellent stability even after repeated use without losing high sensitivity. That is, the purpose is to prevent the occurrence of an abnormal image due to the deterioration of the photosensitive layer film by improving the film quality of the photosensitive member, and to maintain high sensitivity characteristics.
