Abstract
An ink includes a coloring material, one or more organic solvents, a resin particle including a structure unit having a carboxyl group and a structure unit having an alkoxysilyl group, and water. The one or more organic solvents includes at least one organic solvent having a solubility parameter of 8.96 to less than 11.8. The ink has a dynamic surface tension A of 34.0 mN/m or less for a surface life of 15 msec at 25 degrees C. according to maximum bubble pressure technique. The dynamic surface tension A and a static surface tension B of the ink at 25 degrees C. satisfy the following relation: 10.0 percent≤[(A−B)/(A+B)]×100≤19.0 percent.
