An image formation apparatus provided according to the present invention does not generate any printing density streaks in low density areas of an image and is therefore capable of outputting stabilized images without any density unevennesses and density streaks in any tonality. The apparatus is structured so as to correct density signals in accordance with a correction table 1 for indicating the recording characteristics of each of the recording elements of the head and the recording characteristics indicated by this correction table 1, and to drive the recording head in accordance with a correction table 2, which does not allow the fore-going corrections to be made when the density signals are lower than a given density, and the density signals corrected by this correction table 2.
A method for correcting density unevenness for an image formation apparatus, the apparatus having a recording head with a plurality of recording elements arranged therein, each recording element having a recording characteristic, and driving means for driving the recording head, said method comprising the steps of:
