    • PURPOSE: An image forming apparatus providing an improved optical path of a scanner is provided to conveniently increase the capacitance of a black developer. CONSTITUTION: Plural laser scanner units(10,20) includes plural developers(31,32,33,34), a light source and a light reflection unit. The laser scanner units form an electrostatic latent image in photoreceptors(31a,32a,33a,34a) of each developer. The plural laser scanner units have the same focal length as the length from the light source to the photoreceptors. The light reflection unit of one certain laser scanner unit is placed at a position different from the installation position of the light reflection units of the rest laser scanner units.
    • 目的:提供提供扫描仪改进光路的图像形成装置,以方便地增加黑色显影剂的电容。 构成:多个激光扫描器单元(10,20)包括多个显影器(31,32,33,34),光源和光反射单元。 激光扫描器单元在每个显影剂的感光体(31a,32a,33a,34a)中形成静电潜像。 多个激光扫描器单元具有与从光源到感光体的长度相同的焦距。 一个激光扫描器单元的光反射单元被放置在与其余激光扫描器单元的光反射单元的安装位置不同的位置。

    • A color image forming apparatus is provided to concurrently perform a developing process and an intermediate transfer process by using a plurality of laser scanning units. A color image forming apparatus(100) includes a first laser scanning unit and a second laser scanning unit(130). The first laser scanning unit scans a photosensitive drum(140) to form an electrostatic latent image corresponding to at least one of four-color developers on the surface of the photosensitive drum. The second laser scanning unit is located apart from the first laser scanning unit and scans the photosensitive drum to form an electrostatic latent image, which corresponds to at least one of developers other than the developer corresponding to the electrostatic latent image formed by the first laser scanning unit, on the surface of the photosensitive drum.
    • 提供彩色图像形成装置,以通过使用多个激光扫描单元同时执行显影处理和中间转印处理。 彩色图像形成装置(100)包括第一激光扫描单元和第二激光扫描单元(130)。 第一激光扫描单元扫描感光鼓(140)以形成对应于感光鼓表面上的四色显影剂中的至少一种的静电潜像。 第二激光扫描单元位于与第一激光扫描单元分开的位置,并扫描感光鼓以形成静电潜像,其对应于除了与通过第一激光扫描形成的静电潜像相对应的显影剂以外的显影剂中的至少一个 单元,在感光鼓的表面上。
