摘要： An ink set of the present disclosure includes a colored ink jet ink and a decoloring ink. The colored ink jet ink includes a leuco dye, a developer, and a dispersant, and the decoloring ink includes a solvent and water. The solvent includes a specific solvent component that has a Hansen solubility parameter that differs from the Hansen solubility parameter of the developer by an absolute value of less than or equal to 5.3. Preferably, the specific solvent component is a glycol ether or a glycol. Preferably, the leuco dye is a fluoran. Preferably, the developer is a compound containing a phenolic hydroxy group in the molecule.
