PROBLEM TO BE SOLVED: To provide an ink jet recorder and a recovery unit in which an appropriate pressure can be supplied depending on the type of a recording head and ink ejection state of the recording head can be sustained in a normal state. SOLUTION: The ink jet recorder comprises a recovery means 10 for sustaining the ink ejection state of a recording head 3 in a normal state, a capping means 11 capable of forming an enclosed space between the recording head 3 and the capping means 11 by covering the ink ejection opening of the recording head 3, a plurality of pressure generating means 48A and 48B for generating a specified pressure variation in the enclosed space, a means 53 for combining the pressure of the plurality of pressure generating means 48A and 48B, and a means 54 for coupling the pressure combining means 53 with the capping means 11. |
