Definitions
- the present invention relates to a p-ester phenyl compound which has improved solubility in an organic solvent and is useful as a charge transporting agent for an electrophotographic photoconductor, and an electrophotographic photoconductor using the compound.
- Electrophotography generally means that the surface of a photoreceptor made of a photoconductive material is charged in a dark place, for example, by corona discharge, exposed to this, and the charge in the exposed part is selectively dissipated to form an electrostatic charge.
- This is a type of image forming method in which a latent image is obtained, an image is formed using toner, and then transferred and fixed to paper or the like to obtain an image.
- inorganic photoconductive substances such as selenium, zinc oxide, cadmium sulfide, and silicon have been widely used for electrophotographic photoreceptors. These minerals have many advantages as well as various disadvantages.
- selenium has the drawback that it is difficult to produce under conditions that it is easy to crystallize due to heat and mechanical shock.
- Zinc oxide and sulfide dough have problems with moisture resistance and mechanical strength, and are added as a sensitizer.
- There are drawbacks such as deterioration of charging and exposure due to the dye, and lack of durability.
- Silicon is difficult to manufacture and uses highly irritating gas, so it is expensive and sensitive to humidity, so care must be taken when handling it.
- selenium and sulfide domes also have toxicity problems.
- Organic photoreceptors using various organic compounds that have improved the disadvantages of these inorganic photoreceptors are widely used.
- Organic photoreceptors have a charge generator and There are a single-layer type photoreceptor in which a charge transporting agent is dispersed in a binder resin, and a laminated type photoreceptor in which a charge generation layer and a charge transport layer are separated in function. Function-separated organic photoreceptors are widely used because of their wide choice of materials and the relative ease with which photoreceptors with any performance can be made by combining them.
- Examples of the charge generating agent include azo compounds, bisazo compounds, trisazo compounds, tetrakisazo compounds, thiapyrylium salts, squarylium salts, azurenium salts, cyanine dyes, perylene compounds, metal-free or metal phthalocyanine compounds, polycyclic quinone compounds, and thioindigo.
- Examples of the charge transport agent include oxaziazole compounds (Patent Document 1), oxazole compounds (Patent Document 2), pyrazoline compounds (Patent Document 3), hydrazone compounds (Patent Documents 4 to 7), diamine compounds (Patent Document 8), and stilbenes. Compounds (Patent Documents 9 to 11), butadiene compounds (Patent Documents 12) and the like.
- Organic photoreceptors using these charge transport agents have excellent properties and some have been put to practical use, but those that sufficiently satisfy the characteristics required for electrophotographic photoreceptors have not yet been obtained. Not yet. In addition, although various properties such as sensitivity are good, some of them have not been put into practical use due to poor compatibility with resins and poor solubility in solvents.
- Patent Documents 13 disclose compounds such as p-terphenyl compounds, which improve the electrophotographic properties such as durability and sensitivity by being included in the charge generation layer of the laminated photoconductor. It is intended. Further, the p-ter'phenyl compound disclosed in Patent Document 14 is excellent in solubility, but does not have sufficient properties such as durability.
