DEVELOPING-TRANSFERING MODULE AND IMAGE FORMING APPARATUS HAVING THE SAME

摘要

A developing/transferring module and an image forming apparatus having the same are provided to install a middle transferring unit and photosensitive member portions integrally in a sub frame, thereby preventing a color alignment error caused by an assembly process. A developing/transferring module(200) includes a sub frame(210), plural photosensitive member portions, and a middle transferring unit(240). The sub frame is installed detachably on a main frame(110). The plural photosensitive member portions are disposed at regular intervals within the sub frame and have photosensitive members(223) to which developer is attached. The middle transferring unit is installed to be opposite to the plural photosensitive member portions within the sub frame. Developer of the photosensitive member portions is transferred first on the middle transferring unit. The middle transferring unit transfers the first transferred developer to the recording paper of the main frame second.
