摘要： A heating device includes a pair of rotators, a heater, a temperature sensor, a conductor, a conductor support, and a component supporting the conductor. The pair of rotators is in contact with each other to form a nip through which a sheet passes. The heater heats at least one of the pair of rotators. The temperature sensor detects a temperature of the heater. The conductor has flexibility and is coupled to the temperature sensor. The conductor support supports the conductor such that a distance from the conductor to at least one position of the heater outside a predetermined region of the heater in a width direction of the sheet is larger than a distance from the conductor to a position of the heater inside the predetermined region in the width direction. The component has a first side facing the heater and a second side opposite the first side.

摘要： A fixing device includes a first rotator, a second rotator, a heater, a nip formation pad, and a separator. The second rotator contacts an outer circumferential surface of the first rotator to form a nip between the first rotator and the second rotator. The heater includes a resistive heat generator to heat the first rotator. The nip formation pad contacts an inner circumferential surface of the first rotator to form the nip. The separator separates a recording medium passing through the nip from the first rotator. The separator includes a separating surface and a contact. The separating surface is separated from the outer circumferential surface of the first rotator and separates the recording medium from the first rotator. The contact contacts the outer circumferential surface of the first rotator at a position where the first rotator is pinchable between the contact and the nip formation pad.

摘要： A nip forming device includes an endless film and a pressure rotator that presses against a heater via the endless film. A driver drives and rotates the pressure rotator to cause the pressure rotator to drive and rotate the endless film. A controller controls the driver to drive and rotate the pressure rotator, based on a temperature of the pressure rotator, that is detected by a detector, in a forward direction to convey a conveyed object and to interrupt forward rotation of the pressure rotator. In response to a determination that the temperature of the pressure rotator is higher than a predetermined temperature when a job of the nip forming device is finished, the controller controls the driver to drive and rotate the pressure rotator for a predetermined time in a backward direction opposite to the forward direction and to interrupt backward rotation of the pressure rotator.

摘要： A belt device includes a belt, a secured member, a pressure rotator, and lubricant. The belt is rotatable and has an endless shape. The belt includes an inner portion having an inner circumferential surface. The inner portion has an elastic power of 55% or more. The inner circumferential surface of the belt slides on the secured member. The pressure rotator includes a porous elastic body and presses the secured member via the belt to form a nip between the belt and the pressure rotator. The lubricant is interposed between the inner circumferential surface of the belt and the secured member.
