ABSTRACT:
An ink jet recording apparatus, including nozzles each of which ejects a droplet of ink toward a recording sheet and which are arranged in one or more arrays in a first direction; pressure changing devices each of which changes a pressure of the ink to be supplied to a corresponding one of the nozzles so that the one nozzle ejects the droplet of ink, wherein the pressure changing devices are grouped into two groups arranged in a second direction perpendicular to the first direction; two flexible wiring cables which are electrically connected to the two groups of pressure changing devices, respectively, and which extend from the two groups of pressure changing devices in opposite directions, respectively, parallel to the second direction; two driver circuits which are provided on, and electrically connected to, the two wiring cables, respectively, and each of which outputs respective drive signals to drive the respective pressure changing devices of a corresponding one of the two groups; and a heat sink including two heat-conducting side walls which are opposite to each other in the second direction, a portion of each one of the two side walls contacting a corresponding one of the two driver circuits, and a heat-conducting connection portion which extends in the second direction and connects between the two side walls.
