ABSTRACT:
A transfer unit used with an image forming apparatus includes an upper housing having a transfer belt of an endless track structure to transfer an image from a photoconductive unit of a main body of the image forming apparatus, and a plurality of rollers to support the transfer belt to rotate therein, and a lower housing removably connected to the upper housing, and having a cleaning unit to clean the transfer belt. The transfer unit is removably mounted to the main body of the image forming apparatus. Accordingly, the transfer unit is facile to be connected to and separated in a vertical direction from the main body of the image forming apparatus. Further, it is convenient to replace the transfer unit since the relative position thereof can be controlled with respect to a contacting object, such as the photoconductive unit.
