Title:
METHOD FOR WARMING UP FIXING DEVICE
Document Type and Number:
Japanese Patent JP3289141
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To uniformly raise the surface temperature of a pressure roller within relatively short warm-up time.
SOLUTION: In the method for warming up a fixing device 10 provided with a heat roller 2 and the pressure roller 3, on the way detection temperature reaches a fixation standby temperature after first stop control is performed, an aging and stop control consisting of the aging control of rotating both rollers 2 and 3 and the stop control of maintaining both rollers 2 and 3 in a stopped state after executing the control is executed at least once. The aging control is executed so as to displace the nip position to the heat roller 2 of the pressure roller 3 at the time of stopping both rollers 2 and 3 for stipulating aging end in a peripheral direction from the nip position at the time of starting aging.
