    • An image forming apparatus includes a drum cartridge supporting member supporting a plurality of drum cartridges having photosensitive drums. The drum cartridge supporting member is movable between first and second positions inside and outside a main assembly of the image forming apparatus. A guide portion guides a plurality of developing cartridges having developing rollers for developing electrostatic latent images formed on the corresponding photosensitive drums. The guide portion individually guides the developing cartridges to and from the main assembly. A moving mechanism moves the developing cartridges mounted in the main assembly between a developing position in which the electrostatic latent images are to be developed and a retracted position in which the developing cartridges are retracted from the developing position. When the developing cartridges are in the retracted position, the drum cartridge supporting member is permitted to move between the first and second positions.
    • 图像形成装置包括支撑多个具有感光鼓的鼓盒的鼓盒支撑部件。 鼓盒支撑构件可在图像形成装置的主组件内部和外部的第一和第二位置之间移动。 引导部分引导具有显影辊的多个显影盒,用于显影形成在相应的感光鼓上的静电潜像。 引导部分将显影盒单独引导到主组件和从主组件引导。 移动机构将安装在主组件中的显影盒移动到要显影静电潜像的显影位置和显影盒从显影位置缩回的缩回位置。 当显影盒处于缩回位置时,鼓盒支撑件被允许在第一和第二位置之间移动。

    • An image forming apparatus includes an image bearing member; a charging member for contacting a peripheral surface of the image bearing member to electrically charge the peripheral surface; a first developing device for forming a first developed image on the peripheral surface of the image bearing member charged by the charging member; a second developing device for forming a second developed image on the peripheral surface, wherein a combined developed image is formed by superimposing the first developed image and the second developed image on a common transfer material, wherein when the combined image is being formed, the charging member is cleaned by transferring, by an electric field, material deposited on the charging member to a region between the first developed image and the second developed image on the peripheral surface of the image bearing member, and wherein the first developed image and the second developed image are not formed in the region.
    • 图像形成装置包括:图像承载部件; 充电构件,用于接触图像承载构件的外围表面以对外围表面进行充电; 用于在由充电部件充电的图像承载部件的外周表面上形成第一显影图像的第一显影装置; 用于在外围表面上形成第二显影图像的第二显影装置,其中通过将第一显影图像和第二显影图像叠加在共同的转印材料上而形成组合的显影图像,其中当组合图像正在形成时, 通过电场将沉积在充电构件上的材料转印到图像承载构件的外周表面上的第一显影图像和第二显影图像之间的区域,并且其中第一显影图像和第二显影图像 图像不在该区域形成。
