摘要： A silicone rubber roll is characteristically prepared on a metallic center by forming a layer of the cured product of a silicone rubber composition which comprises (A) organopolysiloxane, in which the total amount of low molecular weight siloxanes having a degree of polymerization ranging from 3 to 20 is controlled to be at most 10,000 ppm, (B) reinforcing silica powder with a specific surface area of at least 50 m.sup.2 /g, (C) silicone elastomer particles with an average particle size of 200 .mu.m, in which the total amount of low molecular weight siloxanes having a degree of polymerization ranging from 3 to 20 is 2,000 ppm or less, and (D) a curing agent. The total amount of low molecular weight siloxanes having a degree of polymerization ranging from 3 to 20 within the cured product layer is controlled to be 2,000 ppm or less, since the elimination of the low molecular weight siloxanes having a degree of polymerization ranging from 3 to 20 proceeds effectively during the processes of the silicone rubber composition preparation, forming, and curing. Therefore, the obtained roll is extremely useful for various types of rolls utilized in copying machines which particularly need to avoid the low molecular weight siloxanes.

A rare earth metal-based permanent magnet of the present invention as a means for achieving the objective has a laminated plating film, and is characterized in that the plating film comprises as an outermost surface layer a SnCu alloy plating film having a film thickness in a range from 0.1 μm to 2 μm, the composition of the SnCu alloy plating film is 35 mass % or more but less than 55 mass % of Sn and the rest being Cu, and a base plating film having two or more layers including at least a Ni plating film and a Cu plating film which are formed as the lower layer under the SnCu alloy plating film, and among the base plating film, the Ni plating film is located just below the SnCu alloy plating film. A joined structure fabricated using the rare earth metal-based permanent magnet of the present invention exhibits favorable initial adhesion strength when combined with a silicone-based adhesive, and is less deteriorated in adhesion strength even after a moisture resistance test.
