INKJET RECORDER

PROBLEM TO BE SOLVED: To overcome the problem that, when a waste ink generated during image formation is made to flow downward utilizing a waste ink route having a slope to accommodate the waste ink in a waste ink storage such as a maintenance cartridge, reliability as a waste ink route can not be maintained due to an increase in viscosity and fixing in the middle of the slope, allowing an ink to leak from a body. SOLUTION: In the ink jet recorder, a waste ink discharged by a suction recovery means for recovering a discharge state of a recording head is temporarily made to flow into a waste ink storage for storing the waste ink, and a deposit accumulated in the waste ink route is washed out by making the waste ink flow all at once into the waste ink route having the slope when the waste ink is accumulated to a prescribed amount, and is certainly accommodated in a waste ink storage part on the downstream side.
