In a micro-step drive and driving method of a stepping motor, the stepping motor generates a drive force for movement on a prescribed path of a moving unit provided in an electrically driven device, a standard point and a target point of an operation are set on the path, the stepping motor is rotated such that the moving unit passes through the standard point, a count value of a stable stop point of the stepping motor that is closest to a count value at the point of time when the moving unit passed through the standard point is specified, the specified count value is set as a start point for controlling a rotation angle of the stepping motor, and the stepping motor is rotated, and stopped at the count value of the selected stable stop point.
