Summary:PROBLEM TO BE SOLVED: To output prints without defects even when an intermediate transfer belt has a deteriorated point to be the cause of print defects.SOLUTION: An image forming apparatus 1 comprises: an ILS part 6 that reads a print image from a print in which a toner image of a test pattern on an IBT 21 is transferred to a sheet; deteriorated point specification means 80 that specifies a deteriorated point on the IBT 21 from the test pattern of the print image read by the ILS part 6; and print control means 81 that controls to transfer the toner image onto the IBT without using an area on the IBT 21 including the deteriorated point specified by the deteriorated point specification means 80.SELECTED DRAWING: Figure 3 【課題】中間転写ベルトに印刷不良の原因となる劣化箇所が存在する場合であっても印刷不良のない印刷物を出力する。【解決手段】画像形成装置１は、ＩＢＴ２１上のテストパターンのトナー画像が用紙に転写されて定着された印刷物から印刷物画像を読み取るＩＬＳ部６と、ＩＬＳ部６の読み取った印刷物画像のテストパターンからＩＢＴ２１上の劣化箇所を特定する劣化箇所特定手段８０と、劣化箇所特定手段８０が特定した劣化箇所を含むＩＢＴ２１上の領域を用いずにＩＢＴ上にトナー画像を転写するよう制御する印刷制御手段８１とを有する。【選択図】図３
