摘要： An image forming apparatus including at least first and second developing devices for developing latent images formed on an image bearing member. The first and second developing devices contain developers of different colors, respectively. The second developing device contains a developer of a predetermined color and is fixedly mounted in the image forming apparatus. The first developing device contains a developer of a color other than the predetermined color and is detachably mountable in the image forming apparatus. Only the first developing device is exchangeable.

摘要： In a slit exposure scanning type copying machine or the like, a thin white member is fixedly disposed in the image forming main optical path from the vicinity of the end of an original stopping reference member or the vicinity of the end of an original carriage keep member, whereby the image forming main light beam from said vicinity of the end is not effectively transmitted to an image plane but instead, part of an illuminating light beam for illuminating an original from the opposite sides thereof is reflected by the white member, thereby forming predetermined blank spaces at the end portions of copy paper corresponding to the scanning starting end and the scanning terminating end. The white member is disposed at a predetermined angle with respect to the original by taking the scanning direction into account so that the shadow thereof imparted to the slit exposure area on the original surface does not greatly decrease the quantity of light of the illuminating light beam which contributes to image formation.
摘要翻译：在狭缝曝光扫描型复印机等中，从原始停止基准部件的端部附近或原稿托架保持部件的端部附近固定地配置在成像主光路中的薄白色部件由此，来自所述端部附近的成像主光束不能有效地透射到像面，而是从其相对侧照射原稿的照明光束的一部分被白色部件反射，从而形成预定的对应于扫描开始端和扫描终止端的复印纸的端部处的空白处。白色部件通过考虑扫描方向而相对于原稿设置成预定的角度，使得其赋予原始表面上的狭缝曝光区域的阴影不会大大降低照明光束的光量，有助于图像形成。
