摘要：
One of the two flow passages branches from one of two ink cartridges to one of the two discharging portions and one of the two individual discharging portions. The other flow passage branches from the other ink cartridge to the other discharging portion and the other individual discharging portion. A ratio of frequency of use of each of the discharging portions, Ra, and frequency of use of each of the individual discharging portions, Rb, satisfies Ra:Rb=1:½.
