Description of the Related Art In recent years, due to an increase in the number of durable sheets of a copying machine or the like, a heat fixing roller used for fixing an electrostatic microscope image on a recording material has been stably transported for a long time to perform heat fixing. What can be done is being demanded. However, a conventional roller having a smooth surface may cause paper wrapping at the beginning of copying, or paper dust and toner may collect between the paper and the roller, causing the paper and the roller to slip, resulting in poor paper conveyance. There is a problem. In order to prevent such slippage between the paper and the roller, a method of roughening the surface of the roller by a method such as polishing is conceivable. In this case, however, there is a problem that the roller is worn by the polishing. Further, in the method of polishing the surface of the roller, if the roller is formed of a low-hardness elastic material or the like, the conventional grinding technique cannot cope with the problem, 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, for example, a cover for holding a rod-shaped core metal member on a concentric axis with a cylindrical hole is formed in a molding die having a cylindrical hole penetrating therethrough. A method is known in which an elastic material is poured into a molding die using a molding device provided at both ends of the hole, and then the elastic material is cured and integrated with a core member to produce an elastic roller. Have been. In the case of such a manufacturing method, in order to prevent the paper and the rollers from slipping, the inner surface of the through hole of the molding die must be uniformly roughened or patterned. It is very difficult to process the inner surface of the molding die of a roller that requires a long through hole in the axial direction with conventional processing technology, and even if it is possible, it is impossible to make many identical products with high precision However, there is a problem that economic efficiency is poor.

ることにより得られる。The present inventor has conducted intensive studies to solve the above-mentioned problems of the prior art. As a result, the surface of the elastic layer formed around the rod-shaped core metal member of the heat fixing roller has a high precision geometric shape. If the irregular shape is provided, the paper will not wind around the heat fixing roller, and paper powder and toner, which have conventionally deteriorated the paper transportability, will enter the uneven portion of the elastic layer. The present inventors have found that no slippage between the rollers and the paper occurs, and good paper transport performance can be provided for a long period of time. As a manufacturing method, a lid for holding a rod-shaped core metal member on a concentric axis with the cylindrical hole in a forming die having a cylindrical hole penetrating can be attached to both ends of the cylindrical hole. Using a mold, an elastic material is introduced into the molding die, and the elastic material is cured to form an elastic layer, thereby producing a heat fixing roller. At this time, by using a molding die in which the concave and convex shapes of a desired geometric pattern are transferred in reverse on the inner surface of the molding die, a heat fixation in which the surface of the elastic layer is provided with highly accurate geometric concave and convex shapes. Rollers are manufactured. The molding die having the desired geometric pattern concavo-convex shape transferred on the inner surface of the molding die in the opposite direction, first, a master 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 forming the geometric pattern by uneven etching, electric discharge machining or the like, a mold material is attached and formed around the matrix having the uneven shape by additional processing, and then the mold material is processed into a predetermined molding mold shape. Finally, it is obtained by removing only the master mold.
