A microcomputer control section (76) is such that, when switching is mode from a pain sheet mode to a sheetboard/OHP mode by the operation of a corresponding keys (43) on an operation panel (40), the microcomputer control section changes the control temperature of an upper roller (81) to an equivalent bit value so as to vary that control temperature from 150 DEG C to 160 DEG C during which time the microcomputer control section, confirming the surface temperature of an upper roller (81) from a detection signal of a sensing section (73) through an A/D conversion section (77), turns an upper lamp heater (71) ON through a lamp control section (75) if the surface temperature of the upper roller is below 155 DEG C and, effecting continued confirmation of the surface temperature of the upper roller (81) from the detection signal of the sensing section (73) through the A/D conversion section (77), turns the upper lamp heater (71) OFF through the lamp control section (75) when the surface temperature of the upper roller (81) increases above 160 DEG C, so that a sheetboard/OHP sheet-ready (copyable) state is displayed on a liquid-crystal display section (42) on an operation panel (40). <IMAGE> |
