Abstract
An image forming apparatus that can reduce a difference in fog or image density between two facing pages of a booklet formed after duplex printing is provided. A CCD line sensor inputs a series of pieces of image data whose order of printing has been determined in advance. The CCD line sensor, a first storage section, a second storage section, and a calculation section determine a difference in printing density between the first face and the second face of the printing medium after duplex printing. A judgment section judges whether or not to change the order of printing based on the difference in printing density. A control unit controls the order of printing of the image data based on the judgment. An image forming section, a paper supply section, an image reading section, and an operation section print the image data on the printing medium.
