Abstract:
An ink jet recording apparatus is provided which includes a recording unit including a recording head having a surface provided with an ejection opening therein, an aqueous ink that is ejected from the ejection opening to record an image on a recording medium, a protection unit including a covering member that covers the surface having the ejection opening, and a recovery unit separate from the covering member, having no member that scrapes the ink deposited in the ink receiving member or sucks the ink from the ejection opening. The recovery unit includes an ink receiving member that receives waste ink discharged from the ejection opening according to preliminary ejection data, directly from the ejection opening without interposing any other member. The aqueous ink contains a self-dispersible pigment containing the carboxyl group or the sulfonate group.
