    • An image forming apparatus wherein a latent image is formed on an image bearing member, corresponding to the image information to be recorded by the charging and exposure steps effected to the image bearing member. The latent image is developed, and the developed image is transferred onto a transfer material. The developing device is movable between its operative position where it is capable of developing the latent image on the image bearing member and its inoperative position where the developing device is retracted from the operative position. A control device is provided to effect the movement of the developing device between the operative position and the inoperative position at other than the image exposure step or not during the transfer step.
    • 一种图像形成装置,其中潜像形成在图像承载部件上,对应于通过对图像承载部件的充电和曝光步骤记录的图像信息。 显影潜像,将显影的图像转印到转印材料上。 显影装置可在其能够使图像承载部件上的潜像显影的操作位置和显影装置从操作位置缩回的不工作位置之间移动。 提供控制装置,用于在转印步骤期间,除了图像曝光步骤之外,还可以在显影装置的操作位置和不工作位置之间实现移动。
