An ink set, an inkjet recording apparatus including the ink set, and a method of forming an image using the ink set include a black ink composition comprising a first colorant, water, and a first alkyl ether and a color ink composition comprising a second colorant, water, and a second alkyl ether, wherein an amount of the first alkyl ether based on 100 parts by weight of the black ink composition is at most twice an amount of the second alkyl ether based on 100 parts by weight of the color ink composition. When using the ink set, an image of effective quality may be formed which has a reduced bleeding without decreasing an image density.
