摘要： An image forming apparatus performs a 1-pass recording by a single main scan with respect to a recording medium by a nozzle group including different overlapping nozzles that scan the same overlapping region on the recording medium to record dots. Alternatively, a multi-pass recording is performed by a plurality of main scans with respect to the overlapping region by the same nozzle group or by different nozzle groups. The recording in a central portion of the overlapping region is performed by placing emphasis on the succession or continuity of the dots, while the recording in boundary portions of the overlapping region is performed by placing emphasis on the scattering of the dots.
