Abstract: According to one embodiment, an image processing apparatus includes a detecting unit, a determining unit, and a correcting unit. The detecting unit detects an overlapping portion of a first image printed on a first side of a sheet and a second image printed on a second side opposite to the first side. The determining unit determines whether the detected overlapping portion of the first image and the second image is equal to or larger than a predetermined area. The correcting unit corrects, if the overlapping portion is equal to or larger than the predetermined area, the density of one of the first image and the second image.
