摘要： An optical writing head positioning mechanism includes spacers provided between a latent image carrier for carrying an electrostatic latent image and an optical writing head for exposing the latent image carrier. The spacers each include at least one carrier contact surface that contacts the latent image carrier and at least one head contact surface that contacts the optical writing head to determine an interval between the latent image carrier and the optical writing head. The latent image carrier is in contact with a cleaning member that cleans a cleaning area on a surface of the latent image carrier. In at least one of the spacers, the at least one carrier contact surface includes plural carrier contact surfaces not disposed on edges of the cleaning area, and one of the edges of the cleaning area is located between two adjacent ones of the plural carrier contact surfaces.

摘要： A fixing device includes a drive roller, a driven roller driven to rotate by the drive roller, and a braking force applicator. The driven roller presses against the drive roller to form an area of contact between the drive roller and the driven roller, through which a recording medium bearing a toner image passes. The braking force applicator applies a braking force to the driven roller to generate a shear force between the drive roller and the driven roller. The shear force acting between the drive roller and the driven roller when the drive roller and the driven roller rotate is in a range of from 15N to 25N.

摘要： An image forming apparatus includes an image forming device to form a cleaning toner image in a cleaning region on a cleaning sheet and a check toner image in a check region on the cleaning sheet. The image forming apparatus further includes a fixing device including a first rotator and a heater to heat the first rotator to a cleaning temperature that is lower than a fixing temperature to which the first rotator is heated in a print job and higher than a cold offset temperature at which toner adheres to the first rotator by cold offset. Each of the cleaning region and the check region has a length greater than a circumferential length of the first rotator. The cleaning region and the check region are disposed at a leading section and a trailing section of the cleaning sheet in a cleaning sheet conveyance direction, respectively.

摘要： A fixing device includes a heat conductor disposed opposite an inner circumferential surface of an endless belt to heat the endless belt. A nip formation pad is disposed opposite the inner circumferential surface of the endless belt and presses the endless belt against a pressing rotary body to form a fixing nip between the endless belt and the pressing rotary body through which a recording medium bearing a toner image is conveyed. A support is disposed opposite an inner circumferential surface of the heat conductor and contacts an abutment face of the nip formation pad to support the nip formation pad against pressure from the pressing rotary body. A heat insulator is interposed between the heater and the nip formation pad and the support to shield the nip formation pad and the support from the heater.
