摘要： A fixing device includes an endless belt and an opposed rotary body contacting an outer circumferential surface of the belt. A nip formation pad contacting a first part of an inner circumferential surface of the belt presses against the opposed rotary body via the belt to form a fixing nip between the belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A heat conductor disposed opposite a second part of the inner circumferential surface of the belt not contacted by the nip formation pad is interposed between a heater and the belt to conduct heat from the heater to the belt. A reflector disposed inside the loop formed by the belt reflects light from the heater toward the heat conductor. The reflector and the heat conductor surround the heater.

摘要： A heating device includes an endless belt that rotates and a pressure rotator that rotates in a rotation direction. The pressure rotator contacts an outer circumferential surface of the endless belt to form a nip therebetween, through which a heating target having a particular width in an axial direction of the pressure rotator is conveyed. A heater includes a heat generator that defines a conveyance span in the axial direction of the pressure rotator, where the heating target is conveyed, and a non-conveyance span in the axial direction of the pressure rotator, where the heating target is not conveyed. A non-conveyance span temperature detector is disposed opposite the pressure rotator in the non-conveyance span of the heat generator. The non-conveyance span temperature detector detects a temperature of the pressure rotator.

摘要： A fixing unit includes an endless belt unit accommodating a heat source, a pressure roller to rotate in contact with the fixing belt unit forming a pressure border therebetween, and a heat transfer member heated by the heat source to heat the fixing belt unit. The heat transfer member is secured inside an inner circumferential surface of the fixing belt unit and supports the fixing belt unit. A fixed member is secured inside the inner circumferential surface of the fixing belt unit and is pressed against the pressure roller via the fixing belt unit. The heat transfer member has at least one convex portion partially formed in an outer circumferential surface of the heat transfer member in a rotational direction of the fixing belt unit and a longitudinal direction of the heat transfer member to narrow a gap formed between the heat transfer member and the fixing belt unit.

摘要： An image forming apparatus includes a heating device including a heater, a developing device, and an airflow generation device. The heater includes a base, a heat generator, an electrode portion, and conductive portions. The conductive portions are disposed on one side and another side in a longitudinal direction in a heat generation region and spaced apart in a lateral direction intersecting the longitudinal direction. A maximum total value among total values of squares of current flowing in the conductive portions at longitudinal positions on the one side is larger than that on said another side. The developing device includes a rotating member and sliding portions. A sliding portion having highest temperature in operation is disposed on one side of the developing device being same as the one side of the heater in the longitudinal direction. The airflow generation device generates an airflow toward the one side of the developing device.

摘要： A heater includes a plurality of resistive heat generators electrically connected to each other in parallel. A power supply supplies power to the resistive heat generators. An electric current detector detects an electric current that flows through the resistive heat generators. A voltage detector detects a voltage applied to the resistive heat generators. An electric current controller controls the electric current that flows through the resistive heat generators based on the electric current detected by the electric current detector and the voltage detected by the voltage detector. The electric current detector detects the electric current in a state in which, after the power supply starts supplying the power to the resistive heat generators, an identical waveform of an alternating current supplied to the resistive heat generators continues for a predetermined time period or longer taken for the electric current detector to detect the electric current.
