The density correction method according to the present invention includes recording an image on said recording medium at a predetermined halftone density, measuring record density of a result of recording of the halftone density by a densitometer, raising the relative speed between the recording head and the recording medium when the measured record density is higher than the required density and lowering the relative speed when the measured record density is lower than the required density, recording an image on said recording medium at two or more halftone densities after a set value of the relative speed has been changed, and updating a density conversion table for converting input data in such a manner that the record density of a result of recording substantially coincides with the predetermined density.
