发明名称 FLUID EJECTING APPARATUS AND FLUID EJECTING METHOD
摘要 A fluid ejecting apparatus includes a first nozzle array in which nozzles that eject a first fluid are arrayed in a predetermined direction; a second nozzle array arranged beside the first nozzle array in a moving direction orthogonal to the predetermined direction and in which nozzles that eject a second fluid are arrayed in the predetermined direction; and a control section that repeatedly performs operation for ejecting the fluids from the nozzles while relatively moving the first nozzle array, the second nozzle array, and a medium in the moving direction and operation for relatively shifting a relative position between the first nozzle array, the second nozzle array, and the medium towards one side in the predetermined direction. When performing normal image forming operation, the control section relatively shifts the relative position between the first nozzle array, the second nozzle array, and the medium towards the one side in the predetermined direction by a predetermined transporting distance. When forming a second image using the second fluid over a first image formed using the first fluid, the nozzles used for forming the second image are located towards the one side in the predetermined direction relative to the nozzles used for forming the first image. When performing image forming operation near an edge of the medium, a non-ejection nozzle included in the nozzles and from which the fluids are not ejected is located towards the one side in the predetermined direction relative to the nozzles used for forming the first image and is located towards the other side in the predetermined direction relative to the nozzles used for forming the second image. A length, in the predetermined direction, of a region to which the non-ejection nozzle belongs is an integral multiple of the predetermined transporting distance.
