摘要： In a fixing device, a belt moves in a predetermined direction to heat and melt a toner image on a recording medium. A pressing rotary member is pressed against the belt to form a nip portion to nip and convey the recording medium bearing the toner image. A heating member is fixedly provided inside a loop formed by the belt and faces an inner circumferential surface of the belt. The heating member is heated by a heater to heat the belt. The heating member includes a primary heating portion directly heated by the heater, and a secondary heating portion heated by heat conducted from the primary heating portion. The primary heating portion and the secondary heating portion are provided in a circumferential direction of the heating member. The secondary heating portion has a heat capacity smaller than a heat capacity of the primary heating portion.

摘要： A fixing device includes an endless belt formed into a loop and rotatable in a given direction of rotation. An opposed rotary body contacts the endless belt to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A heater is disposed in proximity to an irradiation span spanning on an inner circumferential surface of the endless belt in a circumferential direction thereof to emit light that irradiates and heats the irradiation span of the endless belt. A shield is interposed between the heater and the irradiation span of the endless belt in a diametrical direction thereof to shield the irradiation span of the endless belt from heated air surrounding the heater.

摘要： An image forming apparatus includes a conveyance passage unit, a fixing device, an optical sensor, a fixing condition adjuster, and a regulator. A recording medium passes through the conveyance passage unit. The fixing device fixes a toner image onto the recording medium. The optical sensor includes a light-emitting device and a light-receiving device to detect smoothness of the recording medium according to strength of light received. The fixing condition adjuster adjusts fixing conditions according to the smoothness detected. The regulator is disposed in the conveyance passage unit to regulate conveyance of the recording medium, such that at least a part of the recording medium passes through an irradiated area including an intersection that is determined by an emission angle of a first optical axis of light emitted by the light-emitting device and a reflection angle of a second optical axis of light received by the light-receiving device.

摘要： An image forming apparatus includes an imaging section and a thermal fixing device. The fixing device fuses a toner image formed by the imaging section onto the recording sheet passing through a fixing nip. The fixing device includes a fixing member, a pressure member, a heater, a temperature sensor, and a temperature controller. The fixing member is rotatable, and the pressure member is pressed against the fixing member to form the fixing nip therebetween. The heater heats at least a portion of the fixing member. The temperature sensor senses a temperature of the fixing member. The temperature controller controls the temperature of the fixing member in at least one of an on-off mode and a PID mode. The temperature controller initially operates in the on-off mode upon entering recovery, and switches to the PID mode when a threshold time has elapsed after entering recovery.

摘要： A fixing device includes a fixing unit, a shearing unit, a detection unit, and a controller. The fixing unit fixes a toner image in place on a printed surface of a recording medium. The shearing unit is disposed downstream from the fixing unit along the media conveyance path to at least partially shear toner from the fixed toner image, so as to create a shorn image area that exhibits a different image density than that of an intact, unshorn image area on the printed surface of the recording medium. The detection unit is disposed at least partially downstream from the shearing unit along the media conveyance path to measure the image densities of the shorn and unshorn image areas. The controller is operatively connected to the fixing unit and the detection unit to adjust one or more operational parameters according to a difference between the measured image densities.
