An ink jet recording device comprises a carriage (5) having a plural number of ink jet recording heads (1, 2, 3, 4) each having a plural number of discharge ports (12, 13, 14, 15) mounted thereon, a means for giving recording ink signals to the ink discharge energy generating elements corresponding to all or a part of the respective plural number of discharge ports of the plural number of discharge heads (1, 2, 3, 4), and a control means, which increases the number of recording heads (1, 2, 3, 4) to be used during recording of the recordable region formed by the total sum of all the discharge regions of the plural number of recording heads from initiation of recording onto a recording medium (1, 2, 3, 4), reducing the number of recording heads (1, 2, 3, 4) to be used during recording of the recordable region in the recording completion region of the recording medium (8), and has one scanning width to be recorded by scanning by the recording head during recording as the feeding pitch of the recording medium (8). |
