Abstract
A driving force transmission mechanism comprising a photosensitive drum driving member, wherein the photosensitive drum driving member is engaged with an image forming apparatus driving member and receives the driving force from the image forming apparatus driving member; the image forming apparatus driving member comprises a triangular groove having a triangular cross-section and driving force transmission portion disposed in three vertex angles of the triangular groove; the photosensitive drum driving member comprises a non-distorting protrusion which is axially extended from the end face of a drum shaft and engaged with the groove on the image forming apparatus driving member; the protrusion has a position-limiting mechanism and a stressed mechanism; a projecting tooth obliquely disposed on said non-distorting protrusion is taken as the stressed mechanism; and each projecting tooth also has a mating surface which is engaged with the driving force transmission component to transmit the driving force.
