ABSTRACT:
A driving apparatus of a detachable developing apparatus, and the detachable developing apparatus using the driving apparatus. The driving apparatus includes: a coupling member including a coupling drive which is connected to a driving element and to which driving power is transferred from the driving element, a coupling gear to which driving power is transferred from the coupling drive, and a coupling disc positioned between the coupling drive and the coupling gear for flexibly connecting the coupling drive and the coupling gear; and a power transferring portion including a plurality of gears to transfer driving power from the coupling member to the developing element and the toner supply element. At least one of the plurality of gears is a reduction gear for reducing a load applied to the coupling member from the developing element and the toner supply element.
