Abstract:
An image forming apparatus including a cartridge including a rotating member, the cartridge including a driving force receiving member, and an apparatus main body to which the cartridge is detachably attachable. The apparatus main body including a driving force transmitting member, an output member, and a biasing member disposed between the output member and the driving force transmitting member, wherein when the cartridge is detached from the apparatus main body and an engagement between the driving force transmitting member and the driving force receiving member is released, the driving force transmitting member is rotated relative to the output member in the predetermined rotation direction by biasing force of the biasing member.

Claim (Index 1):
An image forming apparatus that forms an image on a recording material, the image forming apparatus comprising:\n a cartridge including a rotating member and a driving force receiving member that is rotatable together with the rotating member and is arranged to receive driving force for rotating the rotating member; and an apparatus main body to which the cartridge is detachably attachable, the apparatus main body including,\n a driving force transmitting member arranged to rotate and transmit the driving force to the driving force receiving member, \n an output member rotatable about an axis arranged coaxially with that of the driving force transmitting member, the output member being arranged to transmit the driving force to the driving force transmitting member and to have play between itself and the driving force transmitting member in a rotation direction of the driving force transmitting member, and \n a biasing member disposed between the output member and the driving force transmitting member, the biasing member biasing the driving force transmitting member in a predetermined rotation direction relative to the output member, \n wherein one of the driving force transmitting member and the driving force receiving member includes a plurality of engaging portions, and the other of the driving force transmitting member and the driving force receiving member includes a plurality of engaged portions, the plurality of engaging portions and the plurality of engaged portions engaging with each other so that the driving force transmitting member and the driving force receiving member engage with each other, wherein, in a case where the cartridge is mounted in the apparatus main body the driving force transmitting member and the driving force receiving member are arranged to engage with each other, resulting in a rotation of the driving force transmitting member in the predetermined rotation direction causes the rotating member to rotate, and wherein in a case that the cartridge is detached from the apparatus main body and an engagement between the driving force transmitting member and the driving force receiving member is released, the driving force transmitting member is caused to rotate relative to the output member in the predetermined rotation direction by biasing force of the biasing member.
