Abstract
A driving apparatus includes a driving gear connected to a driving motor, a driven gear engaged with the driving gear, and a driving force coupling part coupling the driving gear and the driven gear to not move with respect to each other. The driving force coupling part includes an axle distance maintaining member to maintain a substantially constant distance between axes of the driving gear and the driven gear. The driving apparatus couples the driving gear and the driven gear to not move with respect to each other when a driving force is transmitted from the driving gear to the driven gear, thereby maintaining a substantially uniform distance between axes of the driving gear and the driven gear. Accordingly, a driven gear shaft is substantially prevented from changing position and deformation of a process cartridge is substantially prevented due to a driving torque of the driving gear and a load torque of the driven gear. Thus, a change in a gap between a developing roller and a photoconductive medium is minimized.
