摘要： A hydrogenated NBR composition comprising 30 to 200 parts by weight of titanium oxide and 1 to 8 parts by weight of magnesium oxide, based on 100 parts by weight of hydrogenated NBR. By forming a crosslinked rubber layer of the rubber composition on a metal plate, a gasket material with excellent blister resistance, whose roll kneadability is improved without reducing the rubber strength of hydrogenated NBR, is provided. Moreover, the rubber composition is effective as a rubber raw material for use in soft metal or a high hardness hydrogenated NBR material for which kneading processing is difficult.

摘要： The charging roll 10 for an electrophotographic device comprises a shaft 12, an elastic layer 14 formed on the outer peripheral surface of the shaft 12, and a top layer 16 formed on the outer peripheral surface of the elastic layer 14. The elastic layer 14 is constituted of a high-resistance first phase 14a in which the surface resistance value is 1.6×1014 Ω·cm to 8.8×1015 Ω·cm (inclusive), and a low-resistance second phase 14b in which the surface resistance value is 1.3×102 Ω·cm to 4.9×103 Ω·cm (inclusive). The second phase 14b contains two types of carbon black: carbon black A, of which the amount of DBP absorption is 115 cm3/100 g to 160 cm3/100 g (inclusive); and carbon black B, of which the amount of DBP absorption is 70 cm3/100 g to 110 cm3/100 g (inclusive).
