Title:
IMAGE FORMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/238856
Kind Code:
A1
Abstract:
An image formation device (2) comprises a fixing belt (240), a heater (241), a pressure roller (242), a fixing motor (243), a temperature sensor (244), an expansion amount estimation unit (34), and a fixing motor control unit (246). The fixing belt (240) fixes a toner image to a sheet S. The heater (241) heats the fixing belt (240). The pressure roller (242) applies pressure to the fixing motor (243). The fixing motor (243) drives the pressure roller (242). The temperature sensor (244) detects the temperature of the heater (241). The expansion amount estimation unit (34) estimates an expansion amount on the basis of the relation between the temperature of the heater (241) and the expansion amount of the pressure roller (242). The fixing motor control unit (246) controls driving of the fixing motor (243) on the basis of the expansion amount of the pressure roller (242).
