The separating claw used in the electrophotographic apparatus of the present invention is
Since a chemisorption film containing a fluorinated alkyl group is formed on the surface by chemical bonding through a siloxane bond, the releasability is excellent. That is, since the fluoroalkyl group is present on the surface layer of the chemical adsorption film, the releasability is excellent and the toner is hard to adhere. In addition, since the base of the chemical adsorption film is formed by chemical bonding (covalent bonding) through a siloxane bond, it is possible to obtain a film having excellent durability, and even when the surface is repeatedly rubbed, The chemisorption film does not easily peel from the surface of the separating nail. Furthermore, since the chemical adsorption film of the present invention is an extremely thin film of nanometer or angstrom unit, it does not impair the mechanical strength and other characteristics of the separating claw. In addition, since the chemical adsorption film of the present invention does not require a baking step, the range of the resin to be used is widened, and at the same time, a high-quality separation claw can be obtained without causing thermal deterioration of the resin during processing.

Further, according to the preferable structure of the present invention in which the chemical adsorption film is a monomolecular film, a thin film having a uniform thickness can be formed, and therefore the dimensional accuracy of the separating claw is not affected. Further, when a chemisorption polymer film is used, the film is slightly thicker than the monomolecular film, but a dense film can be obtained.

Among these, particularly trichlorosilane-based chemical adsorbents, chlorosilyl bonds other than chlorosilyl bonds bonded to hydrophilic groups form intermolecular bonds with adjacent chlorosilane groups and siloxane bonds, so that stronger chemical adsorption is achieved.

Furthermore, if a vinyl group (C = C) or an acetinyl group (ethynyl group) group is incorporated in the fluorinated alkyl chain portion, it can be crosslinked by electron beam irradiation of about 5 megarads after the formation of the chemisorption film. It is also possible to improve the hardness of the chemisorption film itself. The chlorosilane-based surfactant to be used in the present invention is not only linear as described above, but also has a branched shape or a shape in which a fluorinated alkyl group or a hydrocarbon group is substituted on the terminal silicon (for example, R, R 1 , R 2 and R 3 are represented by general formulas R 2 SiCl 2 , R 3 SiCl and R 1 with fluoroalkyl groups or hydrocarbon groups.

When a substance containing a plurality of chlorosilyl bonds such as iCl r (C 2 H 5 ) 3-r (where l is 1 or 2) is chemically adsorbed and then reacted with water, the chlorosilyl bond on the surface becomes hydrophilic. The surface of the separating nail becomes hydrophilic, replacing the silanol bond. Among these substances containing a plurality of chlorosilyl groups, tetrachlorosilane (SiCl 4 ) is preferable because it has a high reactivity and a small molecular weight and can give a silanol bond at a higher density. A chlorosilane-based surfactant containing a fluorinated alkyl group can be chemically adsorbed onto the inner layer film, and the chemisorption film thus obtained has a higher density, so that the function of separability is further enhanced.

Further, the chemical adsorption film formed on the surface of the separation claw used in the electrophotographic apparatus of the present invention can sufficiently exhibit the function even if only one monomolecular chemical adsorption film is formed. To form a single molecule chemisorption film, it is sufficient to chemically adsorb a chlorosilane-based surfactant or a substance containing a plurality of chlorosilyl groups, and then wash it with a non-aqueous solvent without contacting with water. It can be done easily without any steps. Further, it goes without saying that the chemical adsorption film may be a monomolecular film accumulated.
