Abstract:
1. An OA equipment using an elastic member of a semiconductive polymer for at least a part of the constituting members of the OA equipment, the elastic member of the semiconductive polymer comprising a conductive composition containing a binder polymer soluble in an organic solvent and a conductive polymer soluble or capable of forming a colloid solution in the organic solvent or the binder solution, wherein the conductive polymer is dispersed in the binder polymer with a particle diameter of 1 μm or less, or is compatible with the binder polymer, wherein the elastic member satisfies both characteristics of: (A) a variation of 1.5 digit or less between the electrical resistance at an applied voltage of 1V and the electrical resistance at an applied voltage of 133V under an environment of 25° C. and 50% RH; and (B) a variation of one digit or less between the electrical resistance at an applied voltage of 10V under an environment of 15° C. and 10% RH and the electrical resistance at an applied voltage of 10V under an environment of 35° C. and 85% RH.
