Abstract
A method of revising a medium resistance to determine a transfer voltage and an image forming device to perform the same. The method includes supplying a medium recognition voltage to recognize a print medium, and reading medium resistances according to a predetermined reading cycle, calculating an estimated medium resistance based on the read medium resistances, by referring to a pattern of medium resistance in an interval between a time at which the medium recognizing voltage is supplied and a predetermined stabilizing time, and determining a medium resistance to be applied when a transfer voltage is supplied, by comparing the calculated estimated medium resistance with the read medium resistances obtained after the predetermined stabilizing time.
