To prevent evaporation of the solvent in an ink from an ink supply tube and reduce the increase in the viscosity of color inks when a selected mode is switched to a facsimile mode, withdrawal-driving of pumps corresponding to the respective color inks is performed to withdraw the inks in the respective colors into ink cartridges from the respective ink supply tubes. Then, when performing color image recording in a printer mode again, color image recording is started by performing supply-driving of the pumps corresponding to the respective color inks to introduce the respective color inks into the ink supply tubes from the ink cartridges corresponding to the respective colors.
