摘要： An ink discharge device including an ink, an ink discharge head, and a negative pressure generator is provided. The ink comprises water, a colorant, an organic solvent X having a solubility parameter of from 8.9 to 12.0 and comprising no glycol ether compound, and a copolymer comprising a structural unit represented by the following formula (1): where R1 represents a hydrogen atom or methyl group and Y represents an alkylene group having 2 to 18 carbon atoms. The ink discharge head includes a nozzle to discharge the ink, a plurality of individual liquid chambers in communication with the nozzle, a flow-in channel to let the ink flow into the individual liquid chambers, and a flow-out channel to let the ink flow out from the individual liquid chambers. The negative pressure generator is configured to generate a negative pressure that lets the ink flow out from the individual liquid chambers.
