An image forming apparatus comprises a plurality of data output parts for outputting printing data corresponding to a plurality of colors in synchronization with a reference clock signal. A clock control part controls the reference clock signal to be input to the data output parts, respectively. A control part outputs an initial clock signal forming the basis of the reference clock signal and initial data forming the basis of the printing data to the data output parts, and controls the clock control part to output the reference clock signal to the data output parts when the initial data corresponding to the colors corresponding to the data output parts are output to the data output parts. Accordingly, an image forming apparatus which is capable of reducing power wastefully consumed in a data output part and a control method thereof are provided.
