PROBLEM TO BE SOLVED: To provide an image forming device capable of restraining a sheet from adhering to a fixing heating member to heat toner and not being separated therefrom when a toner image is fixed to the sheet and preventing necessary or important information out of document images from disappearing while a user does not notice. SOLUTION: The image concentration of a document at its end is detected from document image data input from an image reader IR by an image information detection part 43. The document image data are written once in a packet memory 44 by a drawing control part 42. When the image concentration is beyond a preset concentration and erase processing is permitted, the image data corresponding to a document image which is erased in an area at its end is written in a page memory 45 to store printed image data therein so that the toner concentration of a printed image at its end is smaller than a preset concentration. |
