An inkjet recording apparatus is adapted to form an image on a printing medium, and recognize an image forming region as a region of pixels having drop amounts unequal to zero in the image. A drop amount increase/decrease controllerexecutes an increase/decrease process of drop amount at a current pixel as a target of the process, in accordance with an attribute of the current pixel when the current pixel is included in the image forming region. Pixels are made of ink discharged from nozzles arrayed in a scan direction perpendicular to a transfer direction of the recording medium. The drop amount increase/decrease controllerexecutes the increase/decrease process of drop amount in a reverse increase/decrease pattern to ink to be discharged from a neighboring nozzle.
