ABSTRACT:
An organic photoconductive (OPC) unit of an image forming apparatus and a gear assembly arranged in the OPC unit. The gear assembly includes a drum gear formed on a flange of an OPC drum, a cleaning gear driven by a receiving power from the drum gear, and at least one idle gear interposed between the drum gear and the cleaning gear and transmitting the rotational force of the drum gear to the cleaning gear. Therefore, it is possible to drive a plurality of additional rollers with a single power source, and easy to connect the OPC drum with the gears when the OPC drum is fitted into the OPC unit. In addition, because the gear assembly is constructed in a compact form, it is possible to reduce the volume of the OPC unit.
