PURPOSE:To prevent white and black stripes at the boundary from being caused by adopting the constitution that the preceding recording range and the next recording range are overlapped in recording a signal with a recording head having plural recording elements and the preceding and next overlapped parts are recorded complementarily. CONSTITUTION:A nozzle array 4 having an arrangement length (b) is scanned in the (x) direction on recording paper 1, fed in the (y) direction and stopped and then the (x) direction scanning is executed again. The advanced distance (c) is made shorter than the length (b) of the nozzle in response to the rugged ness of a joint. The distance (c) of advanced feed to make two dots' share of ruggedness is shorter than the nozzle arrangement length (b) by two dots' share. In using all dots for scanning and advancing the nozzle as it is, hatched parts 13 are recorded overlappingly. Thus, in recording a signal selectively at each dot so as not to cause suck overlap in the preceding and succeeding recording regions, the joint is recorded complementarily.
