    摘要： A modified rubber elastic body 12 has a rubber elastic body 121 having rubber elasticity and a surface-treated layer 122 composed of a cured product of photocurable composition impregnated into the rubber elastic body 121 from the surface thereof. The photocurable composition is configured to include a (meth)acryl monomer, a photopolymerizable polymer having a silicone group and/or a fluorine-containing group and a (meth) acryloyl group in a molecule, and a photopolymerization initiator. An electrophotographic device member can be configured as a roll member 1, a blade member 2, a belt member 3 or the like, and the modified rubber elastic body 12 is used as a material for a portion including the surfaces of the respective members.

    摘要： Provided is a conductive composition that has a high conductivity and from which a coating can be formed easily. Also provided is a conductive film that has a high conductivity and in which electric resistance is less likely to increase even during expansion. A conductive composition is prepared by including an elastomer component, a fibrous carbon material having a graphite structure and a fiber diameter of not less than 30 nm, and a conductive carbon black having a structure. A conductive film formed from the conductive composition. The viscosity of the conductive composition formed into a coating with a solid content concentration of not less than 20% by mass, which is measured with a B-type viscometer with an H7 rotor under the conditions of a temperature of 25°C and a rotation speed of 20 rpm, is not more than 200 Pa·s.
