PROBLEM TO BE SOLVED: To easily obtain a molded product with satisfactory dimensional stability by forming a roller molding space with the help of a cylindrical molding die and a pair of core retaining members and providing a resin injection aperture and a first regulating member in one of the core retaining members and at the same time, providing an air vent and a second regulating member in the other core retaining member. SOLUTION: A molding die 100 best suited for manufacturing an image developing roller or the like which is incorporated into a duplicator and the like consists of a cylindrical mold 13 and a pair of core retaining members 14, by which a roller molding space 15 is formed. One of the core retaining members 14 has a resin injection aperture 16 in which a regulating member 17 is provided. The other core retaining member 14 has an air vent 20 in which a regulating member 21 is provided. When the roller is molded, the regulating member 17 is opened and the regulating member 21 is closed, under which state a heat-curable resin is infected. After that, the regulating member 17 is closed and at the same time, the molding die 100 is heated to cure the heat- curable resin and the regulating member 21 is opened before the end of the heat curing process. |
