More Information
Summary:An image forming apparatus includes a paper reading section, a similarity judgment section, and a control section. Between a downstream side in a paper conveyance direction of the paper feed section and a position where image formation is performed, the paper reading section reads an existing image already formed on a surface opposite to a formation surface of a new image newly formed on paper by an image formation section. Based on image data of the new image and image data of the existing image obtained by the image formation section, the similarity judgment section judges similarity between the both images. The control section, upon judging that the similarity is high, causes a pattern image to be formed on a surface of the paper where the existing image is formed, and upon judging that the similarity is not high, does not cause the pattern image to be formed.
