A driving-transmitter (3,12) and a process cartridge, the process cartridge includes a photosensitive drum (10) and the driving-transmitter (3,12) mounted on the end of the photosensitive drum (10). The driving-transmitter (3,12) includes an fitting part (30,122,123) and multiple protrusions (31,32,33,13) protruding from an end face (124,125) of the fitting part. The multiple protrusions (31,32,33,13) are distributed equiangularly on a circle which is in the end face(124,125) of the fitting part. The center of the circle is on the axis of the fitting part (30,122,123). There is an engaging-part (311) on the farthest end of each protrusion (31,32,33,13) from the axis of the fitting part (30,122,123). An anti-separating groove (312,14,16,17) is provided on the engaging-part (311). |
