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.

摘要： A holding unit turns, while holding a latent image writing unit, centered on a turning axis that is arranged on a main body of an image forming apparatus between an opening position and a closing position with respect to the main body. A positioning unit arranged on the main body positions the latent image writing unit with respect to the image carrier, when the holding unit is at the closing position. A biasing unit biases the latent image writing unit to make a contact with the positioning unit. A shock absorbing unit absorbs a shock received by the holding unit and the latent image writing unit when the holding unit is moved from the opening position to the closing position.
