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.
Claims9
A method of driving a transfer belt comprising:
- driving a transfer belt provided in an image forming apparatus by a distance when the transfer belt has been stopped for a period of time, whereby contact points with a plurality of rollers provided on the transfer belt are varied,
- wherein the driving of the transfer belt comprises:
- a first driving step for entering a standby mode for the time period;
- and
- a second driving step for entering a power-saving mode and proceeding according to a reference time and a number of driving operations of the transfer belt set at a power-saving mode to turn off a high-voltage consuming unit of the image forming apparatus after the standby mode;
- wherein the second driving step further comprises counting the number of driving operations of the transfer belt;
- comparing the counted number with a reference number;
- and
- driving the transfer belt by operating a driving source provided in the image forming apparatus if the counted number is less than a reference number.
