PROBLEM TO BE SOLVED: To improve airtightness of an image forming device further by forming a sealing material in a more uniform height. SOLUTION: In an adhesive arrangement process, on one surface of surfaces facing each other, of a first member 26 and a second member 32, there is arranged a second adhesive material 2 in a circular shape, and moreover a first adhesive material 1, which has a smaller contracting ratio against a pushing pressure than the second adhesive material, is arranged together with the second adhesive material 2 so that a height of the first adhesive material 1 is lower than that of the second adhesive material 2. In a pressurizing process, in order that the first adhesive material and the second adhesive material contact with the other surfaces of the facing surfaces, respectively, the other surfaces are pushed down on the first and the second adhesive materials. In a heating process, the first adhesive material 1 contacting with the other surface is heated partially and gradually melted. A part of the first adhesive material which is heated and melted, is then cooled down. COPYRIGHT: (C)2009,JPO&INPIT
