| description | To improve the accuracy of color shift correction in an image forming apparatus.SOLUTION: An image forming apparatus 1 according to an aspect of the present invention comprises: image forming units 30; a secondary transfer unit 35 that secondarily transfers an image primarily transferred to an intermediate transfer belt 34 to a sheet; a first image position detection unit 37 that, based on a result of detection of a primarily-transferred color shift correction pattern, generates first image position detection data indicating the amount of deviation of a formation position of each color on the intermediate transfer belt 34 from an assumed position; and a control unit that performs control of crimping the secondary transfer unit 35 onto the intermediate transfer belt 34 and conveying the sheet at a timing to transfer the color shift correction pattern to the intermediate transfer belt 34.SELECTED DRAWING: Figure 1
【課題】画像形成装置における色ずれ補正の精度をより向上させる。【解決手段】本発明の一側面に係る画像形成装置１は、画像形成部３０と、中間転写ベルト３４に１次転写された画像を用紙に２次転写する２次転写部３５と、１次転写された色ずれ補正パターンの検出結果に基づいて、中間転写ベルト３４における各色の形成位置の想定位置とのずれ量を示す第１画像位置検出データを生成する第１画像位置検出部３７と、色ずれ補正パターンの中間転写ベルト３４への転写するタイミングで、２次転写部３５を中間転写ベルト３４に圧着し、かつ、用紙を搬送させる制御を行う制御部と、を備える。【選択図】図１ |
