Abstract
A rotation speed of a heating rollerand a pressure rolleris variably controlled by a CPUbased on a sheet size to be printed, a direction the sheet is to be passed, and a number of sheets to be printed. Specifically, variable control of the rotation speeds of the heating rollerand the pressure rollerby the CPUis based on an occurrence of a pass-through areaand a non-pass-though areaby a sheet of recording paper with respect to a roller lengthwise direction (axial direction) of a position at which the sheet of recording paper passes between the heating rollerand the pressure roller, and controlled based on a thermal expansion coefficient of a roller diameter of the non-pass-though areaof the pressure roller
