Description of the Related Art In recent years, due to the increase in the number of durable sheets in copying machines and the like, a heat fixing roller used for fixing an electrostatic latent image on a recording material also stably conveys paper for a long time to perform heat fixing. There is a demand for what can be done. However, with conventional rollers having a smooth surface, paper wrapping occurs at the initial stage of copying, and paper dust, toner, and the like accumulate between the paper and the roller, and the paper and the roller slip, which causes paper conveyance failure. There is a problem. In order to prevent such slipping between the paper and the roller, a method of roughening the surface of the roller by a method such as polishing may be considered, but in this case, there is a problem that the roller is worn by polishing. Further, in the method of polishing the surface of the roller, when the roller is made of an elastic material having a low hardness, the conventional grinding technique cannot deal with it, and the requirements for the surface condition of the roller cannot be sufficiently satisfied. There is a problem.

As described in Japanese Patent No. 4423 or the like, for example, a lid for holding a rod-shaped core metal member concentric with the cylindrical hole is formed in a molding die having a penetrating cylindrical hole. A method is known in which an elastic roller is manufactured by pouring an elastic material into a molding die by using a molding device provided at both ends of the hole and then curing the elastic material and integrating it with a core metal member. Has been. In the case of such a manufacturing method, in order to prevent slipping between the paper and the roller, the inner surface of the through-hole of the molding die must be uniformly roughened or patterned, and compared with the diameter. It is extremely difficult to process the inner surface of the molding die of a roller that requires a long through hole in the axial direction by the conventional processing technology, and even if it can be done, it is impossible to make many of the same thing with high precision. Therefore, there is a problem that the economy is poor.

ることにより得られる。The present inventor has conducted extensive studies to solve the above-mentioned problems of the prior art, and as a result, has achieved a highly accurate geometrical shape on the surface of the elastic layer formed around the rod-shaped core metal member of the heat fixing roller. If the irregular shape is provided, the paper will not be wound around the heat fixing roller, and paper powder, toner, etc., which have conventionally deteriorated the transportability of the paper, will enter into the concave and convex shape of the elastic layer. The present invention has been completed based on the knowledge that the roller and the paper do not slip and the paper can have a good paper conveying performance for a long period of time. As a manufacturing method thereof, a molding for holding a rod-shaped core metal member concentric with the cylindrical hole in a molding die having a penetrating cylindrical hole can be attached to both ends of the cylindrical hole. A heat-fixing roller is manufactured by using a mold and introducing an elastic material into the molding mold to cure the elastic material to form an elastic layer. At that time, by using a molding die in which the concave and convex shape of the desired geometric pattern is transferred to the inner surface of the molding die, the heat fixing in which the highly precise geometric uneven shape is provided on the surface of the elastic layer Rollers are manufactured. For the molding die in which the concavo-convex shape of the desired geometric pattern is transferred to the inner surface of the molding die, first, a mother die having the same outer shape as the desired heat fixing roller is manufactured, and the desired shape is formed on the surface of the mother die. After the geometrical pattern is formed by concavo-convex etching, electric discharge machining, etc., a die material is attached and formed around the mother die having an irregular shape by additional processing, and then the die material is processed into a predetermined molding die shape. Then, finally, it is obtained by removing only the matrix.
