Abstract
In a structure which includes a second tank for reserving a predetermined amount of ink to be supplied to a printing head and in which a supply system is configured such that ink is intermittently supplied to the second tank from a first tank, a high charging efficiency to and shortened processing time for charging the second tank, and high overall usability of ink are achieved. In an orientation upon using the printing apparatus, a port of a channel located at the second tank side for supplying ink from the first tank to the second tank is arranged relatively high position and an outlet port for supplying ink from the second tank to the head is arranged relatively low position in relation to the direction of gravity, and a port of the channel located at the first tank side is arranged at the bottom of the first tank.
