Abstract

A gear power transfer mechanism for driving a developing unit in an image forming apparatus wherein the developing unit is selectively located closely to and separated from a photoconductive drum unit in conjunction with opening and closing operations of a cover. This gear power transfer mechanism includes a first bevel gear provided on a rotation axis on a side of the photoconductive drum unit coupled with a drive motor, a second bevel gear always engaging with the first bevel gear, a third bevel gear provided on a rotating axis on a side of the developing unit, a fourth bevel gear always engaging with the third bevel gear and a rotation coupling device coupling the second bevel gear and fourth bevel gear. The rotation coupling device has a coupling structure which transfers rotation of the second bevel gear to the fourth bevel gear and allows movement of the fourth bevel gear relative to the second bevel gear when the developing unit is selectively located closely to and separated from the photoconductive drum unit.
