Moving unit and image forming apparatus

In a moving unit, a shutter member is provided with a first contact portion configured to receive a force in a predetermined direction when the shutter member comes into contact with the apparatus main body, and a second contact portion configured to receive a force in a direction different from the predetermined direction when the shutter member comes into contact with the apparatus main body. When the moving unit is moved from the second position to the first position along the first direction, the first and second contact portions sequentially come into contact with the apparatus main body, the shutter member moves relative to the delivery member in the order of a second direction intersecting the first direction, and the first direction, and the opening changes from the closed state to the open state.
