Image forming apparatus that corrects sheet curl by printing on the edges of the reverse side of the sheet

摘要

An image forming apparatus comprises a printer configured to print the display image on a first surface of paper in a case of simplex printing; a curl suppression image determination section configured to determine, in simplex printing case, a printing position and a printing pattern of a curl suppression image for suppressing the curl of the paper caused by the display image based on an analysis result of a display image analysis section which analyzes the printing range and the density of the display image for each page; and a curl-preventive image addition setting section configured to set image information of the printing position and the printing pattern of the curl suppression image which is determined by the curl suppression image determination section and is supposed to be printed on a second surface of the paper with color erasable material by the printer section.
