Zusammenfassung:To correct a defect such as dirt when there is one on a sheet on which a new image is printed and print the new image.SOLUTION: An image forming apparatus comprises: a correction area determination unit that analyzes first image data corresponding to acquired sheets for printing and determines a correction area; a correction signal generation unit that generates a second exposure signal for correction based on the determined correction area; an output control unit that generates a third exposure signal after correction obtained by correcting a first exposure signal generated from print data of a print job with the second exposure signal; and an image forming unit that forms an image on a sheet based on the third exposure signal.SELECTED DRAWING: Figure 4 【課題】新たな画像を印刷する用紙に、汚れ等の不良がある場合に、これらを修正するとともに新たな画像を印刷する。【解決手段】画像形成装置は、取得した印刷用の用紙それぞれに対応する第1画像データを解析し、補正領域を決定する補正領域決定部と、決定された補正領域に基づいて、補正用の第2露光信号を生成する補正信号生成部と、印刷ジョブの印刷データから生成した第1露光信号を、第2露光信号で補正した、補正後の第3露光信号を生成する出力制御部と、第3露光信号に基づいて、用紙に画像を形成する画像形成部と、を備える。【選択図】図4
