前記レジストレーション補正手段は、前記画像坦持体上にレジストレーション補正マークを形成するように前記各画像形成手段を制御するパターン形成手段と、前記レジストレーション補正マークを検出するマーク検出手段と、前記マーク検出手段の検出結果に基づいて前記各ライン間のレジストずれを補正することを特徴とする画像形成装置。Image forming means for forming an image with a plurality of lines as a set in the axial direction of the image carrier, transport means for transporting a transfer material onto which the image is transferred, and image formation for forming an image with the plurality of lines as a set In an image forming apparatus having registration correction means for correcting registration deviation of each line of the means,
The registration correction means includes a pattern forming means for controlling each of the image forming means so as to form a registration correction mark on the image carrier, a mark detection means for detecting the registration correction mark, and An image forming apparatus, wherein a registration error between the lines is corrected based on a detection result of a mark detection unit.
前記画像担持体上に画像の位置合わせのためのマークを形成するべく前記画像形成手段を制御する制御手段と、Control means for controlling the image forming means to form a mark for image alignment on the image carrier;
前記画像担持体上に形成されたマークを転写位置にて転写するように移動する転写ベルトと、A transfer belt that moves to transfer a mark formed on the image carrier at a transfer position;
前記転写ベルト上のマークの位置を検出する検出手段とDetecting means for detecting the position of the mark on the transfer belt;
前記検出手段による検出出力に基づいて、レジストずれ要素を補正する補正手段とを備え、Correction means for correcting the resist misalignment element based on the detection output by the detection means,
前記制御手段は、第1のレーザビームのみを使って、第1のマークを形成し、次に、第2のレーザビームのみを使って第2のマークを形成するように制御し、The control means controls to form the first mark using only the first laser beam, and then forms the second mark using only the second laser beam;
前記検出手段による第1のマークと第2のマークの検出出力に基づいて、前記補正手段は第1と第2のレーザビーム間のレジストずれ要素を補正することを特徴とする画像形成装置。The image forming apparatus according to claim 1, wherein the correction unit corrects a resist misalignment element between the first and second laser beams based on detection outputs of the first mark and the second mark by the detection unit.
