| titleOfInvention | Process for producing conductive rolls for electrophotographic equipment |
| abstract | In a urethane foam layer, the electrical resistance can be reduced, the change in conductivity due to durable use is less likely to occur, and the variation in electrical resistance in the urethane foam layer can be suppressed, and the conductivity for electrophotographic equipment. A method for producing a sex roll is provided. A prepolymer obtained by reacting the following components (A), (B), and (F) at a specific ratio with a premix obtained by mixing each component excluding the following (F) component at a specific ratio: To prepare a composition for urethane foam layer 2 so that the content ratio of the following component (G) in the composition for urethane foam layer 2 is in the range of 0.05 to 10% by weight, A urethane foam layer 2 is formed on the outer peripheral surface of the shaft body 1. (A) A polyether polyol having an EO unit of less than 30 mol% and an Mw in the range of 1000 to 6000. (B) A polyether polyol having an EO unit of 50 mol% or more and an Mw in the range of 3000 to 15000. (C) Carbon black. (D) Foaming agent. (E) Catalyst. (F) Isocyanate. (G) Ionic conductive agent.
