A polyol-crosslinkable fluororubber composition comprises 100 parts by weight of polyol-crosslinkable fluororubber ; 0.5 to 10 parts by weight of a perfluoroalkane represented by the general formula F(CF2)2nF (n : 5~30), a 1H-perfluoroalkane represented by the general formula F(CF2)mH (m : 10 ~30), or a mixture thereof ; 0.5 to 2 parts by weight of basic magnesium aluminum hydroxycarbonate hydrate ; and 1 to 5 parts by weight of an acid acceptor compound excluding Ca compounds. The fluororubber composition can simultaneously attain improvement in preservation stability of compounds, prevention of compounds from adhesion at the time of kneading, short-time vulcanization, improvement of mold releasability at the time of vulcanization molding, prevention of contamination with metal ions and reduction in adhesiveness of crosslinking products due to increase of crosslinking density without substantially impairing the normal state physical properties or compression set characteristics and further advantage-ous properties inherent in the fluororubber, and contains no calcium compounds causing contamination of HDD.
An ink container, adapted to supply an ink composition to an ink jet recording apparatus including a recording head for discharging the ink composition, includes an ink chamber containing the ink composition, the ink chamber including a wall defining the ink chamber and a support connected to an inside of the wall to support the wall; and an ink pouring port through which the ink composition is poured into the ink chamber, in which, in a case where the ink chamber is filled with the ink up to 50% of the volume thereof, an area of the support in contact with the ink composition is smaller than an area of the support in contact with atmosphere.

An ink composition of the invention is an ink composition to be charged in an ink storage container which includes an ink composition-replenishable ink chamber and an ink inlet, and the ink chamber is able to communicate with outside air. The ink composition includes a pigment; an organic compound; and water, and a resolubility index is 0.5 to 10 minutes, the resolubility index indicating a time required for that after the mass of the ink composition is decreased by 50%, the viscosity thereof is returned to an ink viscosity before the mass is decreased by addition of water in an amount equivalent to the decreased mass.
