PROBLEM TO BE SOLVED: To efficiently aggregate a plurality of original images while securing legibility.SOLUTION: An image forming apparatus 100 includes: an effective image extracting part 113 which extracts an effective image from an original image; a division determination part 114 which determines whether or not the original image of a processing object is dividable on the basis of a position of an effective image region comprising a plurality of effective pixels included in the original image of the processing object; a division processing part 115 for dividing the original image having been determined to be dividable into a plurality of original images; and a rotation processing part 116 which applies rotation processing to the original image having been determined not to be dividable. The effective image extraction part 113 erases the original image when an effective image region is not included in the divided original image, and when the original image having been subjected to the rotation processing is determined not to be dividable, extracts the original image as an effective image.SELECTED DRAWING: Figure 1 【課題】複数の原稿画像を判読性を確保しつつ効率的に集約する。【解決手段】画像形成装置１００は、原稿画像から有効画像を抽出する有効画像抽出部１１３と、処理対象の原稿画像に含まれる複数の有効画素からなる有効画像領域の位置に基づいて、処理対象の原稿画像が分割可能であるか否かを判定する分割判定部１１４と、分割可能であると判定された原稿画像を複数の原稿画像に分割する分割処理部１１５と、分割不可であると判定された原稿画像に回転処理を施す回転処理部１１６と、を備え、有効画像抽出部１１３は、分割された原稿画像に有効画像領域が含まれない場合には、この原稿画像を消去し、回転処理が施された原稿画像が分割不可であると判定された場合には、この原稿画像を有効画像として抽出する。【選択図】図１
