Disclosed is an image formation apparatus. The image formation apparatus includes: a main body in which a driving shaft is supported; a driving coupler having a cylindrical body coupled to one end of the driving shaft, and an axial protrusion protruding in the direction from the body to the driving shaft; and a development cartridge including a driven coupler coupled to the driving coupler when mounted in the main body. When the driving coupler is rotated in a first direction, a locking protrusion protruding from the axial protrusion of the driving coupler in a first direction of the driving shaft is locked by being inserted into a locking groove dented in a first direction of the driving shaft of the driven coupler, and one side of the axial protrusion of the driving coupler and a delivered side of the driven coupler, which corresponds to the one side, come in contact with each other to rotate the driven coupler in the first direction. 화상형성장치가 개시된다. 본 화상형성장치는, 구동축이 지지되는 본체, 구동축의 일단에 결합되는 원기둥형의 몸체와, 몸체로부터 구동축 방향을 따라 돌출된 축방향돌기를 갖는 구동커플러 및 본체에 장착 시, 구동커플러에 결합하는 피동커플러를 포함하는 현상 카트리지를 포함하고, 구동커플러가 제1 방향으로 회전 시, 구동커플러의 축방향돌기에서 구동축의 제1 방향으로 돌출 형성된 록킹돌기가 피동커플러의 구동축의 제1 방향으로 오목하게 형성된 록킹홈에 삽입되어 록킹되고, 구동커플러의 축방향돌기의 일측면과 일측면에 대응되는 피동커플러의 피전달면은 서로 접촉하여 피동커플러를 제1 방향으로 회전시킨다.
