According to one embodiment, an inkjet image forming apparatus includes an inkjet head which ejects an aqueous ink, a recording medium reversing mechanism for reversing a recording medium, and a controller. The controller performs control such that if a both-side recording mode is designated, the location information of an overlapping region of images to be recorded on the front surface and the rear surface is detected, based on the detected recording image location information on the front surface and the rear surface, the density of the images to be recorded at the location on the front surface and the rear surface is determined, and if the image density on one surface is higher than the image density on the other surface, the image density at the location on the one surface is reduced, and controls the inkjet head based on the control.
