1. An image forming apparatus comprising:
a single driving source for driving first and second supply containers each for supplying a developer to a developing device; and a drive switching device for switching a drive transmission path so that power from said driving source is selectively transmittable to the first and second supply containers, wherein said drive switching device includes: a rotatable driving member rotatable in a normal direction and a reverse direction by switching a driving direction of said driving direction; a rotatable swinging member rotatable by rotation of said rotatable driving member and swingable between a first connected position where said rotatable swinging member is connected, by rotation of said rotatable driving member in a first direction, with the first supply container to permit drive transmission and a first retracted position where said rotatable swinging member is retracted from the first supply container by rotation of said rotatable driving member in a second direction opposite to the first direction; and a rotatable moving member movable between a second connected position where said rotatable moving member is connected, by rotation of said rotatable driving member in the second direction, with the second supply container to permit drive transmission from said rotatable swinging member swung to the first retracted position to the second supply container and a second retracted position where said rotatable moving member is retracted from the second supply container by rotation of said rotatable driving member in the first direction. |
