A first region is defined on the head face so as to include a first group of nozzles among all nozzles formed with a recording head. A first amount is defined as a difference between a first reference position at which a leading edge of a recording medium situated at a recording start position is placed and a first shifted position at which the leading edge of the recording medium, which has been most shifted in a subscanning directions and most inclined within a feeding tolerance of a feeder, is placed. A first virtual leading edge is defined at a position where is shifted from the first reference position to a downstream side of the subscanning directions by the first amount. A second virtual leading edge at a position where is shifted from the first reference position to an upstream side of the subscanning directions by the first amount. A first type of recording is performed with the first group of nozzles, when an end of the first region in the upstream side of the first directions is situated at the first virtual leading edge. A second type of recording is performed with all the nozzles, when the end of the first region in the upstream side of the first directions is situated at the second virtual leading edge.
