There is provided an MRI apparatus that is capable of imaging ON/OFF in response to a biological gating signal and changing conditions for imaging, even while the moving bed imaging is performed, and further reducing a load on a subject to be examined, which is caused by fluctuations in the bed moving velocity. A controller that controls a bed to transport the examined subject in a static magnetic field and a unit to apply an RF magnetic field and a gradient magnetic field for imaging configures settings so that the bed moving velocity is kept constant considering an entire imaging time, and further controls the magnetic applying unit for applying the RF magnetic field and the gradient magnetic field so that a moving velocity of the FOV (imaging area) in the subject coordinate system is made different from the bed moving velocity.
