ABSTRACT:
Image forming equipment for performing a predetermined image forming operation by use of a stepwise drive source such as a stepping motor or pulse motor. Either one of a recording medium and a record head is driven by a pulse motor, and whether or not it has reached a predetermined position is determined. While such a decision as to the position of the recording medium or the record head is under way, the displacement per step is changed over to a displacement per step smaller than a displacement to be effected while the predetermined image forming operation is under way.
