Abstract
A structure which includes a container 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 container from an ink tank as an ink supply source makes it possible to reduce the time for charging the container with ink. A member for holding ink and generating a negative pressure originating from an elastic force is provided in the container. With connecting the tank and the member, the pressure in the container is reduced to cause the member to expand, thereby introducing ink into the same. This introduction is stopped by regulating the expansion with a displaceable unit. A negative pressure is generated in the member by canceling regulation by the unit to put it in equilibrium with an ink meniscus holding ability of the printing head.
