Claim:
1. An ultraviolet curable ink jet composition which is stored in a storage body and comprises: a plurality of polymerizable compounds having a vinyl ether group and a (meth)acryloyl group; a photopolymerization initiator; a color material; and water, wherein an amount of the water is greater than or equal to 0.05 mass % and less than or equal to 1.0 mass % with respect to a total amount of the composition, wherein a total amount of the polymerizable compounds in the ultraviolet curable ink jet composition is greater than or equal to 35 mass % and less than or equal to 95 mass % with respect to a total amount of the ultraviolet curable ink jet composition, at least one of the polymerizable compounds has the following formula: where R an amount of the compound represented by formula (1) is greater than or equal to 10 mass % and less than or equal to 30 mass % with respect to a total amount of the ultraviolet curable ink jet composition, an amount of the photopolymerization initiator is 5.0 mass % to 20 mass %, an amount of the color material is 0.5 mass % to 10 mass %, and the color material is a pigment.
