Abstract
To provide a method of effectively reducing the amount of ink droplets remaining on a nozzle surface after a cleaning operation, and an inkjet recording apparatus capable of shortening an entire processing time of an initial filling operation and a cleaning operation by shortening an ink discharge operation time. By providing a partition wall so that a suction port and an atmosphere opening port provided on a back side of a porous sheet placed in a cap are not directly communicated with each other, in an ink discharge operation in the cap, air having entered through the atmosphere opening port flows through a space between the porous sheet and the nozzle surface, and thereafter, flows to the suction port via the porous sheet. Therefore, ink droplets remaining adhering to the nozzle surface can be removed using the force of air flow.
