Image forming apparatus and method

A method of forming an image on a recording medium by using coloring materials of a plurality of colors including at least cyan, magenta and yellow, the method comprising the steps of:

• forming cyan recording pixels on the recording medium with a cyan recording head having a plurality of cyan recording elements;
• forming magenta recording pixels on the recording medium with a magenta recording head having a plurality of magenta recording elements;
• forming yellow recording pixels on the recording medium with a yellow recording head having a plurality of yellow recording elements, a density of the plurality of yellow recording elements arranged in the yellow recording head being lower than each of a density of the plurality of cyan recording elements arranged in the cyan recording head and a density of the plurality of magenta recording elements arranged in the magenta recording head;
• and
• controlling the cyan recording pixels forming step, the magenta recording pixels forming step and the yellow recording pixels forming step in such a manner that a recording density of the yellow recording pixels formed on the recording medium in the yellow recording pixels forming step is lower than each of a recording density of the cyan recording pixels formed on the recording medium in the cyan recording pixels forming step and a recording density of the magenta recording pixels formed on the recording medium in the magenta recording pixels forming step.
