    • In an image forming apparatus for forming a color image by superimposing one toner on another of a plurality of colors, a positional relationship among the image forming parts for different colors is critical. It is difficult to have a positional relationship within a desired limit among image scanning units, if a plurality of image scanning units are mounted on separate mount plates as in the above-described image forming apparatus. This may cause a color aberration. In order to obtain an image forming apparatus to solve the issue, an apparatus having high mounting accuracy of scanning unit is provided.
    • 在通过将一种调色剂叠加在多种颜色之上形成彩色图像的图像形成装置中,用于不同颜色的图像形成部件之间的位置关系是关键的。 如果将多个图像扫描单元安装在如上述图像形成装置中的分离的安装板上,则难以在图像扫描单元之间具有期望的限制内的位置关系。 这可能会导致色差。 为了获得解决问题的图像形成装置,提供了一种具有高扫描单元安装精度的装置。

    • An image forming apparatus includes a substantially horizontally arranged image bearing member; a developing unit, including a plurality of developing devices and supporting the developing devices rotatably relative to the image bearing member; a movable intermediate transfer belt supported by first and second rotation members and facing the developing unit; a primary transfer member forming, together with the image bearing member, a primary transfer portion located near the first rotation member in a moving direction of the intermediate transfer belt, through the intermediate transfer belt; and a secondary transfer member forming, together with the second rotation member, a secondary transfer portion through the intermediate transfer belt. A toner image formed on the image bearing member by the developing unit is transferred on the intermediate transfer belt at the primary transfer portion, and is transferred on a recording material at the secondary transfer portion.
