ABSTRACT:
An apparatus and method of driving a transfer belt are disclosed. The apparatus and method comprise driving the transfer belt provided in an image forming apparatus by a predetermined distance when the transfer belt has been stopped for a predetermined time, and thus varying the contact portion with a plurality of rollers provided on the transfer belt. Image contamination due to deformation on the belt can be avoided. Additionally, because the rotation time of the driving source can be set to a predetermined time during the power-saving mode, power consumption can be minimized.
