1. An ink composition comprising:
a pigment; a copolymer comprising a phosphoric acid group or phosphonic acid group; a hydrosoluble solvent; and water, wherein the pigment is represented by the following chemical formula 1 and satisfies the following relation 1:
Y/X≦0.20 Relation 1 where X represents a peak intensity at a Bragg (2θ±0.2°) angle in a range of 2θ of from 26.5° to 27.5° and Y represents a peak intensity at a Bragg (2θ±0.2)° angle in a range of 2θ of from 11.0° to 11.5° to a CuKα X-ray having a wavelength of 1.541 Å. |
