Abstract:
A charging roller has a roller main body including a cylindrical inner layer having a porous structure formed of a semiconductive rubber composition constituted by ethylene propylene rubber, paraffin oil, and a carbon black having a DBP oil absorption amount of 400 cm 3 /100 g or more and an outer layer constituted by a nonporous and seamless semiconductive tube including a polyurethane thermoplastic elastomer having a type A durometer hardness of 93 or less, carbon black, and crosslinked PMMA particles having an average particle size of 5 to 20 μm. The production method includes a process in which a semiconductive rubber composition forming the inner layer is foamed with OBSH.

Claim (Index 19):
A method of producing the charging roller according to  claim 3 , comprising:\n a process in which the inner layer is foamed by thermal decomposition of 4,4\u2032-oxybisbenzenesulfonyl hydrazide as a foaming agent contained in the semiconductive rubber composition such that it has a porous structure.
