摘要： PROBLEM TO BE SOLVED: To print a high-quality image by reducing a deterioration in image quality, which is caused by the poor measurement of detection of a mark. SOLUTION: This inkjet recording apparatus, which moves the recording medium by detecting the mark recorded on a recording medium, records the predetermined mark on the recording medium with predetermined timing by moving the recording medium along a sub-scanning direction with respect to a recording head which is moved along a main scanning direction, and controls the movement of the recording medium on the basis of a position wherein the mark is detected by a mark detecting means. In the detection of the mark, the inkjet recording apparatus computes the target movement amount of the recording medium on the basis of the position wherein the mark is detected. In the detection of the mark, the inkjet recording apparatus compares the computed target movement amount with a predicted movement amount which is prestored as the target movement amount of the recording medium, and switches the movement amount of the recording medium to either the computed target movement amount or the predicted movement amount, in accordance with the result of that comparison.
