Abstract
An image-forming apparatus is provided which is capable of forming a high-quality image without adverse effect (deterioration in printing precision) which may be caused by a dimensional error in producing ink ejection orifice rows, an error in arranging the ink ejection orifice rows, an error in delivering a recording medium, or a like error. With the apparatus employing six rows of ink ejection orifices, an image is formed by ejecting the ink from the third row of the six ink ejection orifice row numbered in the delivery direction onto a raster line zone L, ejecting the ink from the fifth row onto a raster line zone L, ejecting the ink from the sixth row onto a raster line zone L, ejecting the ink from the fourth row onto a raster line zone L, ejecting the ink from the second row onto a raster line zone L, and ejecting the ink from the first row numbered in the recording medium delivery direction onto a raster line zone L
