Abstract:
1. An ink jet recording apparatus for effecting recording using a recording head for ejecting ink, said ink jet recording apparatus comprising: heating means for heating said recording head; detecting means for detecting a temperature of said recording head; setting means for setting a target temperature of said recording head; control means for controlling the temperature of said recording head to be above the target temperature; and timing means for measuring a time period during which the detected temperature of said recording head is above the target temperature, wherein said control means controls the temperature by heating control for heating said recording head above the target temperature and then effecting diffusing control to permit the heat to diffuse in said recording head, and wherein said control means effects the diffusing control during a period from the heating control to a start of a recording operation, and enables the diffusing control until the time period measured by said timing means during which the temperature of said recording head is above the target temperature becomes greater than a predetermined time period.
