    Abstract: PROBLEM TO BE SOLVED: To provide a semiconductive vulcanized rubber molded product and a semiconductive rubber roll using it having excellent (1) semiconductivity, (2) environment dependency, (3) compression set property, (4) low hardness, (5) storage stability, (6) photoreceptor anti-stain properties (inhibition of blooming onto the semiconductive vulcanized rubber molded product surface), and (7) polishing workability of the semiconductive vulcanized rubber, without containing N-cyclohexylthio phthalimide. SOLUTION: The semiconductive vulcanized rubber composition comprises (a) 100 pts.wt. of an epihalohydrin rubber, (b) 0.1-5 pts.wt. of an organozinc compound, (c) 0.1-5 pts.wt. of 1,8-diazabicyclo(5,4,0)undecene-7 and/or its salt, (d) 0.1-10 pts.wt. of a quinoxaline vulcanizing agent, and (e) 1-10 pts.wt. of an acid acceptor, which is at least one kind selected from the group consisting of a metal oxide, a metal hydroxide, and microporous inorganic crystals.
