IMAGE FORMING APPARATUS AND POWER TRANSMISSION ASSEMBLY OF THE SAME

摘要

PURPOSE: An image forming device and a power transmission structure of the same are provided to transmit driving power from a driving coupling to a driven coupling when a rotation axis is dislocated. CONSTITUTION: One or more driven couplings(45) are connected to a rotation body of a developing cartridge. A coupling holder(120) receives and connects the driven couplings and driving couplings(110) in order that the rotation power of one or more driving couplings is transmitted to the driven couplings. A driving coupling includes a first sphere unit(112). A driven coupling includes a second sphere unit(45a).
