ABSTRACT:
A method of driving a print head and an image forming apparatus employing the same are provided, wherein recording elements of the print head are divided into n groups and are driven to print an image on a medium, wherein recording elements from the respective n groups, that is, one recording element from each of the n groups, are simultaneously driven and a driving order of the recording elements is arranged such that printing positions of the recording elements in each group form a plurality of oblique lines as a medium is fed. Accordingly, the plurality of recording elements, which are divided into a plurality of phases, are non-sequentially driven and therefore, the power consumption due to the driving of the recording elements and degradation of print quality can be reduced.
