A recording apparatus has M different color recording heads (i.e., M columns) which are disposed parallel to each other such that they extend perpendicularly to a main scanning direction and such that two adjacent recording heads are spaced apart by an L-dot interval from each other. At the same time, the M recording heads are offset from each other by l-dot intervals. Each recording head has N nozzles which are spaced apart by K-dot intervals from each other along the subscanning direction. The recording apparatus satisfies either the inequality lM</=K (where K/N is an irreducible fraction) or inequalities lM>K and K(N-1)+1>l (where K/l is an irreducible fraction), thereby preventing double recording (so that only a single nozzle injects an ink onto a single point on a recording paper sheet) and omissions.
