Abstract:
1. A developing unit for mounting to a mounting frame in an image forming apparatus, where the mounting frame has a driving unit for transferring a driving force to the developing unit, a supporting protrusion and a supporting unit for supporting the developing unit, the developing unit comprising: a developing unit main body having a front side and an outer side surface with a supporting groove for contacting the supporting protrusion when the developing unit is mounted on the mounting frame to support the main body, wherein the supporting groove is formed on both outer side surfaces of a front end portion of the developing unit main body, and the photoconductor is disposed at a back end portion of the developing unit main body; the photoconductor rotatably disposed in the developing unit main body and having a supporting shaft with opposite ends supported by the supporting unit; and a driven unit disposed in the developing unit main body and meshing with the driving unit when the developing unit main body is mounted to the mounting frame, wherein one of side surfaces of the developing unit main body includes an interference unit that interferes with the mounting frame and to push the developing unit main body in a transverse direction with respect to a mounting direction into engagement with the driving unit when the developing main body is mounted on the mounting frame.
