PROBLEM TO BE SOLVED: To provide a recording device which makes it possible to measure an accurate OD value by correcting irregularity in an optical sensor of reflecting type by adjusting an installing height of the optical sensor of reflecting type. SOLUTION: A distance between a recording medium and an detecting means is adjusted when OD value of image recorded on the recording medium by a recording head is to be optically detected by a detecting means such as an optical sensor of reflecting type.
