A method of driving and controlling a stepping motor having stationary field poles corresponding to N phases (N: an integer greater than or equal to 4) in which the stationary field poles are successively driven for m steps in such a manner that a number n, ranging form 1 to (N-2), of phases are driven at a time. In this method, after the completion of excitation of an (m-1)th step, stationary field poles are driven with respect to a number of phases larger than n to a desired value set between the stability points of the m-1)th step and the mth step.
