Abstract
A method for correcting a recording head is provided to solve the problems of density unevenness in recorded images. The density comparison is made with the reference density for a predetermined unit in the density distribution of an image recorded by the application of n kinds of signals. Then, one of the n kinds of signals which is close to the reference density is selected. The properties of the signal thus selected are transmitted to the recording head together with the correction data, hence correcting density unevenness.
