Abstract:
An ink jet recording apparatus includes: a container to store ink; a detector to detect a remaining ink amount; a liquid feeding unit to supply the ink to the container; an energy generation unit to cause the ink to be discharged; a storage unit to store correspondence information in which driving information for driving the energy generation unit is associated with each piece of time information indicating a supply time taken to supply the ink; and a setting unit to set new driving information using the correspondence information when an actual supply time is different from the supply time indicated by the time information associated with current driving information among the pieces of time information. The actual supply time indicates a time period from when the liquid feeding unit starts supplying the ink until the detector detects that the remaining ink amount is equal to or higher than a threshold.
