PROBLEM TO BE SOLVED: To reduce generation of banding. SOLUTION: Sub scanning feeding is executed with a constant F dot feeding amount. With the nozzle pitch defined as k dots (k is an integer of 3 or more), the number of nozzles used in one time main scanning N (N is an integer of 3 or more), and parameters Na, Nb, m, L satisfy the following formulae (1)-(4): N=Na+Nb...(1), Na=m×k±1...(2), Nb=Rd[L×Na÷k]...(3), F=Na...(4). Here, m is an integer of 1 or more, and L is an integer satisfying 1≤L<k, respectively. The operator Rd [] represents the calculation of rounding the decimal part of the value in the brackets.
