摘要： A heating device includes a planar heater, a rotator, a pressure rotator, a heating device frame, a resistor, and a discharger. The pressure rotator has a conductive outer surface and presses the rotator. The heating device frame holds the pressure rotator. The discharger is in contact with the conductive outer surface of the pressure rotator and grounded via the resistor and the heating device frame.

摘要： A planar heater includes a base, a resister pattern, a conductor pattern, a power supply electrode, and a base pattern. The base includes a surface portion made of an insulative material. The resistor pattern is on the base. The conductor pattern is on the base and electrically coupled to the resistor pattern. The power supply electrode is electrically coupled to the conductor pattern. The base pattern is on the base and made of a material different from a material of the surface portion of the base to print visible identification information.

摘要： An image forming apparatus includes an image bearer, a protectant applicator, a heating device, and a protectant biasing member. The protectant applicator applies protectant to the image bearer. The heating device includes a heater including a base, a heat generator, an electrode, and a conductor coupling the heat generator to the electrode. The heater has a first position and a second position having a higher temperature than the first position. These are symmetrical to each other with respect to a longitudinal center of a heat generation area of the heater. The protectant biasing member biases the protectant to the protectant applicator with a first biasing force at a position closer to the first position than to the second position and with a second biasing force larger than the first biasing force at a position closer to the second position than to the first, and the protectant contacts the protectant applicator.

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.

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

摘要： A fixing device includes a first rotator, a second rotator disposed opposite the first rotator to form a nip with the first rotator, a heater including a base and a heat generator, and a non-contact temperature detector to detect a temperature of the heater. The heater contacts an inner circumferential surface of the first rotator. The non-contact temperature detector is disposed opposite the inner circumferential surface of the first rotator via the base and disposed at a predetermined distance from the heater.

摘要： A heating device includes a belt that rotates in a rotation direction and has a temperature decrease span in an axial direction of the belt, where the belt is susceptible to temperature decrease. A resistive heat generator is disposed opposite the belt. The resistive heat generator heats the belt and extends in the axial direction of the belt. The resistive heat generator includes a primary heat generating portion that generates heat in a first heat generation amount and a secondary heat generating portion that is disposed outside the primary heat generating portion and disposed opposite the temperature decrease span of the belt. The secondary heat generating portion generates heat in a second heat generation amount that is greater than the first heat generation amount of the primary heat generating portion.

摘要： A fixing device includes a heater including a heat generator that is divided into a plurality of heat generating portions in an axial direction of the endless belt. The heat generator defines a dividing region between adjacent ones of the plurality of heat generating portions and a non-dividing region other than the dividing region. A primary guide contacts and guides the endless belt. The primary guide is disposed opposite the dividing region of the heat generator and has a first thermal capacity. A secondary guide contacts and guides the endless belt. The secondary guide is disposed opposite the non-dividing region of the heat generator and has a second thermal capacity that is greater than the first thermal capacity.
