    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 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.

    摘要: An image writing unit causes, upon being set in a write position, an optical system unit to be movable and positions the optical system unit, with a hitting portion of the optical system unit hitting a blocking portion in a chassis. A holding unit includes, in a state in which the image writing unit is set in the write position, a portion defining an opening that faces either one of an air intake unit and an air exhaust unit. The air intake unit blows an intake air to the optical system unit through the opening, or the air exhaust unit draws an exhaust air around the optical system unit through the opening.

    摘要: A heating device includes: a pair of rotators to form a nip; a heating source having a heat generation area to heat at least one rotator; temperature sensors to detect a temperature of the heating source, a member in contact with the heating source, or one rotator; and a sheet sensor to detect a sheet passing through the nip. The temperature sensors include: a first temperature sensor closer to one end than a center of the heat generation area in the longitudinal direction; and a second temperature sensor closer to the center than the first temperature sensor is. The second temperature sensor is at a position shifted from the center of the heat generation area toward the first temperature sensor. The sheet sensor is on a side opposite a side on which the first temperature sensor is disposed with reference to the center of the heat generation area.

    摘要: A conveyance device includes a first temperature detector and a second temperature detector that detect a temperature of a heater. A recording medium detector detects a recording medium. The first temperature detector is separated from a center position of an elastic layer of a pressure rotator farther than the second temperature detector is in an orthogonal direction perpendicular to a recording medium conveyance direction. The first temperature detector is separated from the center position for a first length and disposed in a first span defined by the center position in the orthogonal direction. The recording medium detector is disposed in a second span opposite to the first span, separated from the center position for a second length smaller than the first length, and disposed in a minimum recording medium conveyance span where the recording medium having a minimum width in the orthogonal direction is conveyed.

    摘要: A heating device includes a first temperature sensor and a second temperature sensor that detect a temperature of at least one of a first rotator, a second rotator, and a heater that heats at least one of the first rotator and the second rotator. The first temperature sensor is disposed outboard from an increased conveyance span where an increased size sheet having an increased width in a longitudinal direction of the heater is conveyed. The second temperature sensor is disposed outboard from a decreased conveyance span where a decreased size sheet having a decreased width in the longitudinal direction of the heater is conveyed. The decreased conveyance span is smaller than the increased conveyance span. The second temperature sensor is disposed within the increased conveyance span and disposed opposite the first temperature sensor via a center of the increased conveyance span in the longitudinal direction of the heater.
