<P>PROBLEM TO BE SOLVED: To provide a conductive composition for electrophotographic equipment, capable of achieving both of superior sagging resistance and low hardness after crosslinked as well as achieving both of reduction in contaminating property and improvement in a crosslinking speed by suppressing generation of a crosslinking residual component, and further reducing a volume resistivity and showing excellent tensile strength after crosslinked. <P>SOLUTION: A base layer 14 of a conductive roll 10 to be used for electrophotographic equipment is formed of a crosslinked body of a conductive composition, which is prepared by compounding (b) a peroxide crosslinking agent together with a specified amount of (c) a specified maleimide compound into (a) an ionic conductive rubber. (c) The specific maleimide compound is, for example, 4,4'-bismaleimide diphenylmethane or 3,3'-dimethyl-5,5'-diethyl-4,4'-bismaleimide diphenylmethane. <P>COPYRIGHT: (C)2012,JPO&INPIT |
