To solve the problem of generation of a large density difference in a final color image due to formation of a part with a low printing density generated by LED array arrangement irregularity at the same position of a recording medium by each imaging mechanism in a color image recording apparatus comprising a plurality of imaging mechanisms for transferring onto a recording medium a toner image formed on a photosensitive member exposed by an LED head comprising a plurality of LED arrays in series.

Image deterioration is restrained by dispersing a part with a low printing density generated by each imaging mechanism by arranging imaging mechanisms 2, 3, 4, 5 having an LED head 16 by 0.5 m from each other in a Y axis direction orthogonal to a recording medium paper conveyance direction F.
