Abstract
An ink jet recording apparatus for recording information by ejecting ink fluid on a recording medium includes a recording head, a cap, an ejection restoration mechanism, an atmospheric air opening mechanism and a heating mechanism. The recording head has an orifice and ejects ink fluid from the orifice. The cap covers up a face on which the orifice of the recording head is disposed. The ejection restoration mechanism performs procedures for keeping a state of ejection of ink fluid by the recording head to be good by discharging ink fluid into the cap. The atmospheric air opening mechanism makes an inside of the cap opened to an atmospheric air when the restoration operations are being performed by the ejection restoration mechanism. The heating mechanism heats the recording head at least before the restoration operation is performed by the ejection restoration mechanism.
