PROBLEM TO BE SOLVED: To prevent overflow of color ink to a pixel on which a background image is not printed, and to achieve good image quality. SOLUTION: The liquid injector includes a conveying mechanism of a medium, a head having a first nozzle row for delivering first liquid forming a background and a second nozzle row for delivering second liquid forming an image on the background, a moving mechanism for moving the head, and a controller for controlling so that a dot row in which dots are arranged in the moving direction is formed on the medium. The controller is set so that an overlap use nozzle is included in the downstream side of the use nozzle of the first nozzle row and the upstream side of the use nozzle of the second nozzle row, and when the dot row for the image is formed by the overlap use nozzle of the second nozzle row, the first liquid is delivered from the use nozzle of the first nozzle row to the dot row for each of several dots, and the dots for the background are intermittently formed in advance, and then, after conveying the medium, the first liquid is delivered from another overlap use nozzle in the first nozzle row, and dots are compensated, and the dot row for the background is formed in advance.
