Abstract
In an image forming device, a ground-tint detection unit detects a ground-tint pattern in an original image based on image data output from an image reader unit. An image invalidation unit outputs a processed image data that makes the image data of the original image illegible, when the ground-tint pattern in the original image is detected. A resolution setting unit allows a resolution of the image reader unit to be higher than a minimum resolution needed for detection of a ground-tint pattern and stored in a memory unit.
