摘要： A heater for being attached to a heating device includes a base layer and a heat generator, an electrode, and a feeder that are mounted on the base layer. The feeder is interposed between the electrode and the heat generator. The feeder is configured to electrically connect the electrode to the heat generator. The base layer includes a heat generating portion mounting the heat generator and an electrode portion mounting the electrode. A decreased cross section portion is interposed between the heat generating portion and the electrode portion. The decreased cross section portion has a cross-sectional area that is smaller than a cross-sectional area of the heat generating portion. The decreased cross section portion includes a positioner configured to engage a counterpart of the heating device and position the heater in a longitudinal direction of the heater when the heater is attached to the heating device.

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.

摘要： A fixing device includes a fixing belt formed into a loop rotatable in a predetermined direction of rotation and a pressure roller disposed opposite the fixing belt. The pressure roller includes a shaft fixedly positioned and a deformable elastic layer. A fixing pad is disposed inside the loop formed by the fixing belt and separably pressed against the pressure roller via the fixing belt to form a fixing nip between the fixing belt and the pressure roller, through which a recording medium bearing a toner image is conveyed. A biasing member biases the fixing pad and the fixing belt against the pressure roller. A stopper restricts motion of the fixing pad biased by the biasing member. The stopper contacts the fixing pad while the recording medium bearing the toner image is conveyed through the fixing nip.

摘要： A belt device includes an endless belt and a rotary driver contacting an outer circumferential surface of the belt to drive and rotate the belt. An opposed belt support is disposed opposite the rotary driver and in contact with an inner circumferential surface of the belt. A rotary belt support is disposed opposite the rotary driver via the opposed belt support and in contact with the inner circumferential surface of the belt. A belt support holder holds the opposed belt support and the rotary belt support to retain a predetermined interval between the opposed belt support and the rotary belt support. A biasing assembly presses against the belt support holder to move the opposed belt support and the rotary belt support collectively with respect to the rotary driver and bias the opposed belt support against the rotary driver.

摘要： A belt device includes a support and a support roller that support a belt. A driven gear is mounted on one of a plurality of shafts of the support roller. A driving gear meshing with the driven gear at a mesh position transmits a driving force to the support roller through the driven gear to rotate the support roller. An elastic bearing rotatably bearing each of the plurality of shafts of the support roller has an inner diameter smaller than an outer diameter of the shaft of the support roller. The bearing includes a slit defining a part of the bearing in a circumferential direction thereof. The slit is disposed upstream from the mesh position in the direction of rotation of the support roller such that the mesh position and the slit define a circumferential angle not smaller than about 20 degrees.
