An inkjet recording apparatus is made capable of preventing ink from sticking during inactivity of the apparatus and, when viscosity of ink contained in a main ink container has fallen outside an appropriate range of viscosity, adjusting ink viscosity to fall within the appropriate range. The apparatus is configured to perform repetitively supplying a solvent contained in a solvent container to the print head and letting the solvent flow back to an ink container through a circulation path and a collection path at intervals of a certain period of time during inactivity of printing by the print head through controlling the print head and a main body. The apparatus is configured as below: when viscosity of ink measured by a viscosity measurement unit is higher than a predetermined range set beforehand, with the print head being put in place in a head receptacle unit, the apparatus discards a part of the ink contained in the ink container flowing through a supply path and into the head receptacle unit via the print head and supplies the solvent contained in the solvent container to the ink container, thereby decreasing viscosity of ink contained in the ink container.
