Abstract

A fusing device, method and computer readable medium including a fusing roller which fuses toner images on a sheet; a pressure roller which contacts the fusing roller with pressure; and a driving device for driving the fusing and pressure rollers; wherein the driving device drives the fusing and pressure rollers so as to satisfy the following inequality: EQU D.sub.fr /D.sub.pr <N.sub.pr /N.sub.fr, where D.sub.fr is a diameter of the fusing roller, D.sub.pr is a diameter of the pressure roller, N.sub.fr is a number of rotations of the fusing roller, and N.sub.pr is a number of rotations of the pressure roller.
