Abstract

A recording head is provided with an ink ejection surface and a cleaning liquid supply surface. The ink ejection surface includes a nozzle region in which a plurality of ink ejection nozzles for ejecting ink onto a recording medium are open. The cleaning liquid supply surface is provided, with respect to the nozzle region, on an upstream side in a wiping direction in which a wiper wipes the ink ejection surface, and a plurality of cleaning liquid supply ports for supplying a cleaning liquid are open through the cleaning liquid supply surface. On the cleaning liquid supply surface, at least in a region including the cleaning liquid supply ports, a hydrophilic region having wettability with respect to water higher than that of the ink ejection surface is formed substantially evenly across an entire region in a width direction thereof orthogonal to the wiping direction.

Description

technical field [0001] The present invention relates to a recording head having ink jet nozzles for ejecting ink onto a recording medium such as paper, and an ink jet recording device including the recording head. Background technique [0002] As recording devices such as facsimile machines, copiers, and printers, inkjet recording devices that eject ink to form images are widely used because they can form high-definition images. [0003] In such an inkjet recording device, tiny ink droplets (hereinafter referred to as spray) ejected together with ink droplets for image recording and rebound spray generated when the ink droplets adhere to the recording medium are adhered and solidified on the recording head. inkjet surface. As the spray on the ink ejection surface gradually increases and is stacked on the ink ejection nozzles, the linearity of the ink deteriorates (flying) or non-ejection occurs, thereby degrading the printing performance of the recording head. [0004] In ...
