Generation of an artifact in an image under a transition state up to a steady state is suppressed and image quality is improved by executing the following pulse sequence. In the coherent SSFP method, a gradient magnetic field is applied so that an integrated value of time of a gradient magnetic field in a slice selection direction becomes a predetermined value which is not zero in a repetition time. Specifically, a gradient magnetic field Gs.sub.2 for correcting phases of spin dispersed by a gradient magnetic field Gs.sub.1 for selecting the slice of an inspected object 40 is applied with an integrated value of time obtained by subtracting a difference value S so as become smaller than a half value of an absolute value of integrated values of time of the gradient magnetic field Gs.sub.1. Then, after a reading time, a gradient magnetic field Gs.sub.3 to be applied so as to cancel the gradient magnetic fields Gs.sub.1 and Gs.sub.2 is applied with the same integrated value of time as that of the gradient magnetic field Gs.sub.2.
