To specify a spot of an image formation apparatus having a factor of the density deviation.SOLUTION: An image formation apparatus 10 outputs the fact that there is a factor leading to the density deviation in an image formation part 2 when the patch number input from a user by looking at a diagnostic chart 12 formed by the image formation part 2 is not included in a prescribed range set based on a reference patch number, and outputs the fact that there is a factor leading to the density deviation in an image reading part 4 when the density of at least one patch image in a sample chart read by the image reading part 4 is not included in a preset density range for each patch image in a case where the patch number is included in the prescribed range.SELECTED DRAWING: Figure 3 【課題】濃度ずれの要因を有する画像形成装置の箇所を特定する。【解決手段】画像形成装置１０は、ユーザが画像形成部２によって形成された診断チャート１２を見て入力したパッチ番号が、基準パッチ番号に基づいて設定された規定範囲に含まれない場合、画像形成部２に濃度ずれにつながる要因があることを出力し、パッチ番号が規定範囲に含まれる場合には、画像読み取り部４で読み取った見本チャートにおける少なくとも１つのパッチ画像の濃度が、パッチ画像の各々に対して予め設定されている濃度範囲に含まれない場合、画像読み取り部４に濃度ずれにつながる要因があることを出力する。【選択図】図３
