    摘要: A fixing device includes an endless belt that rotates and a pressure rotator that rotates and presses against the endless belt to form a fixing nip between the endless belt and the pressure rotator, through which a recording medium bearing an image is conveyed. A heater is disposed inside a loop formed by the endless belt. The heater heats the endless belt. A conductor is disposed upstream from the pressure rotator in a recording medium conveyance direction and grounded. The conductor contacts and detects the recording medium.

    摘要: A heater includes a first heat generator and a second heat generator each of which has a hypothetical center line that divides each of the first heat generator and the second heat generator into a first section and a second section. A first conductor connects a first electrode to the first heat generator and the second heat generator. A second conductor connects a second electrode to the first heat generator and the second heat generator. A first primary connector connects the first conductor to the first section of the first heat generator. A second primary connector connects the first conductor to the second section of the second heat generator. A first secondary connector connects the second conductor to the first heat generator. A second secondary connector connects the second conductor to the second heat generator.

    摘要: A heater includes a base and at least one resistive heat generator mounted on a face of the base. At least one electrode supplies power to the at least one resistive heat generator. A conductor couples the at least one electrode with the at least one resistive heat generator. A slide layer covers the at least one resistive heat generator and the conductor. The slide layer includes a projecting portion that defines a surface of the slide layer. The projecting portion is defined by a film thickness of at least one of the conductor and the at least one resistive heat generator. The projecting portion includes an upstream projection disposed opposite a lateral end of the base in a longitudinal direction of the base and a downstream projection disposed downstream from the upstream projection in a rotation direction of an endless belt that slides over the heater.
