1. An inkjet recording apparatus that performs inkjet recording on a recording medium in a recording region, comprising:
a recording head that includes an ejection port surface where an ejection port for ejecting ink is provided, the recording head being movable within a range including the recording region and a non-recording region where the recording is not performed;
a carriage that supports the recording head;
a carriage moving unit that moves the carriage;
a cap capable of setting the ejection port in a capping state in the non-recording region;
a blade that is placed between the recording region and the cap in a moving direction of the recording head, the blade being capable of wiping the ejection port of the recording head in a case where the recording head moves from the non-recording region to the recording region;
a blade moving unit capable of moving the blade up and down, the blade moving unit being capable of moving the blade to a first position where an upper edge of the blade is at a higher level than the ejection port surface and to a second position where the upper edge of the blade is at a lower level than the ejection port surface; and
a control unit configured to control the recording head, the carriage moving unit, and the blade moving unit,
wherein in a case that the control unit causes the carriage moving unit to move the recording head from the recording region to the non-recording region, the control unit causes the blade moving unit to place the blade at the second position in a state where the ejection port surface and the blade are at positions overlapping with each other in the moving direction, and
wherein the control unit causes the blade moving unit to place the blade at the first position in an event where the control unit causes the recording head to perform preparatory ejection, the preparatory ejection being to eject ink from the ejection port to the cap that is not in the capping state.
