Title: Thermal fixing device and image forming apparatus
Inventor: SENDA SEIICHI
IPC: G03G15/20
Filed: 2002-03-29
Abstract: <P>PROBLEM TO BE SOLVED: To make it possible for a thermal fixing device having at least two heaters, one of which heats the middle of a heat roller and the other of which heats the ends thereof, to speedily resume thermal fixing with appropriate temperatures of the middle and ends after the drive of both the heaters are turned off.  <P>SOLUTION: First, in S100, it is determined whether the temperature of the middle of the heat roller is higher than 100°C or not. If the temperature is higher than 100°C, the step proceeds to S110, in which the side heater is turned on and the center heater is turned on two seconds later after that. By turning on the side heater and then the center heater two seconds later thereafter, as in S110, a temperature difference between the heaters can be decreased to 8 to 13°C at a point in time when the center heater is tuned on. Because both the ends of the heat roller are heated earlier than the middle of it, the temperature difference between the ends and the middle can be decreased in comparison to the case where the center heater and the side heater are turned on at the same time.  <P>COPYRIGHT: (C)2004,JPO
