Abstract
An inkjet recording apparatus that the throughput until a start of a recording operation in the structure in which an ink is circulated between a recording head and an ink tank includes the recording head which discharges the ink to perform a recording operation, the ink tank which stores the ink, and a buffer chamber having a volume which is changed according to a pressure. When the inkjet recording apparatus is changed from a circulation state in which a supply pump and a collection pump are driven to circulate the ink between the recording head and the ink tank to a pause state in which the driving of the supply pump and the collection pump is stopped to stop the circulation of the ink, a negative pressure due to a change in the volume of the buffer chamber is maintained.
