Abstract
In an image forming apparatus, a 2D code detecting unit detects a 2-dimensional code in a document image to be printed. A divisional code distributing unit (a) removes the 2-dimensional code in the document image, (b) divides the 2-dimensional code into a predetermined number of divisional codes, (c) performs a zooming process and/or a rotation process for a part or all of the divisional codes, (d) distributes the divisional codes after the zooming process and/or the rotation process, and (e) generates and outputs a decode key that includes (e1) the number of the divisional codes, (e2) positions of the divisional codes, and (e3) a zooming ratio of the zooming process and/or a rotation angle of the rotation process. A printing device prints the document image in which the divisional codes are distributed.
