Abstract

Abstract Translated from Japanese (57)【要約】 【目的】この発明は、色ずれを低減してコンパクトで安 価に実現するを目的とする。 【構成】 この発明は、像担持体21上に書き込み装置 23で複数色の画像を書き込んで潜像を形成し、これら の潜像を現像装置25,28により複数色のトナーでそ れぞれ現像して転写部材に転写する画像形成装置の書き 込み位置の自動調整方法であって、像担持体21に書き 込み装置23で所定の画像を書き込んで潜像を形成し、 この潜像に現像装置25,28で複数色のトナーを付着 させてトナー像を形成し、このトナー像に対して光学セ ンサ42により光を照射してその総合反射光を検出し、 この検出結果によって書き込み装置23の像担持体21 に対する書き込み位置を調整する。 (57) [Abstract] [Object] An object of the present invention is to realize a compact and inexpensive device by reducing color misregistration. According to the present invention, a writing device 23 writes an image of a plurality of colors on the image carrier 21 to form latent images, and the latent images are developed by developing devices 25 and 28, respectively, with toners of a plurality of colors. A method for automatically adjusting a writing position of an image forming apparatus for transferring to a transfer member, in which a writing device 23 writes a predetermined image on the image carrier 21 to form a latent image, Toner images of a plurality of colors are attached to the latent image by the developing devices 25 and 28 to form a toner image, and the toner image is irradiated with light by the optical sensor 42 to detect the total reflected light. Based on this detection result, the image carrier 21 of the writing device 23 Adjust the writing position for.
