The power consumption of the entire recording apparatus is decreased in the structure that the recording element and the light emitting portion are provided on the ink tank, processes according to the amount of the residual ink is performed by communicating information stored in the recording element to the main body of the recording apparatus, and the condition of the ink tank can be informed by emitting light. The ink tank comprises the recording element, the light emitting portion, and the controlling portion driving the the recording element and the light emitting portion at the appropriate timing, and further comprises the voltage level chanigng menas for supplying the appropriate voltage to each thereof. Relatively low voltage is constantly supplied to the controlling portion, thereby driving the recording element and the light emitting portion at the appropriate timing. Accordingly, appropriate processings can be divided according to necessary events during the series of processings for the recording apparatus, thereby realizing the power saving effect.
