摘要： A pressurizing unit includes a contact-pressure member for pressurizing an endless belt, a holding member that holds the contact-pressure member, and a biasing member that presses both ends of the holding member. The biasing member presses the holding member, so that a direction in which the biasing member presses the holding member is substantially the same as a direction in which the holding member presses the pressure-contact member.

摘要： A temperature control method for use in a fixing device that fixes a toner image on a recording sheet by passing the recording sheet through a fixing nip defined between a fixing member and a pressure member includes temperature detection, heater control, and duty control execution. The temperature detection detects a temperature of the fixing member with a temperature detector. The heater control controls operation of a heater of the fixing device by changing a duty thereof according to the detected temperature. The duty control execution executes a heater duty control to change a heater duty for a current control cycle discontinuously from that for a previous control cycle when the current control cycle precedes entry of the recording sheet into the fixing nip by a given period of time.

摘要： A fixing device includes a fixing rotator, a pressure rotator, a pressure plate, a pressing force, an entrance guide, an exit guide, and a transmission. The pressure rotator presses the fixing rotator to form a nip between the fixing rotator and the pressure rotator. The pressure plate rotates about a fulcrum to press the pressure rotator. The pressing force adjuster adjusts a pressing force of the pressure rotator. The entrance guide guides a recording medium entering the nip. The exit guide guides the recording medium ejected from the nip. The transmission transmits a displacement of the pressure plate to the entrance guide and the exit guide.
