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 separator presser that presses against a plurality of separators to separate the plurality of separators from a fixing rotary body that contacts an opposed rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image passes. A single driver is connected to the separator presser to separate the separator presser from the plurality of separators. An entering recording medium detector is disposed upstream from the fixing nip in a conveyance direction of the recording medium to detect the recording medium. A controller is connected to the driver to control the driver based on a detection signal sent from the entering recording medium detector to change a contact time period for which the plurality of separators contacts the fixing rotary body.

摘要： An image forming apparatus includes a pressing device, an apparatus body, an opening body, and a vibration insulator. The pressing device housed in the apparatus body is configured to press a pressing body to a pressing target body. The opening body is configured to open and close to the apparatus body. The opening body presses a pressing target portion of the apparatus body, at a first pressing portion to cancel a pressing state of the pressing device by opening of the opening body and at a second pressing portion to enter the pressing state of the pressing device by closing of the opening body. The vibration insulator is provided on at least one of the pressing target portion and the second pressing portion, at a contact portion at which the pressing target portion contacts the second pressing portion when the first pressing portion cancels the pressing state.

摘要： A fixing device includes a belt, an opposed rotator, a nip formation pad, a heater, a stay, and a positioner. The nip formation pad has a plurality of projections in a longitudinal direction of the nip formation pad. The positioner is disposed between the nip formation pad and the stay to position the nip formation pad. The positioner has a plurality of insertion holes arranged in a longitudinal direction of the positioner to accept the projections and restrict movement of the nip formation pad with respect to the positioner in a rotation direction of the belt and a direction opposite the rotation direction. The plurality of insertion holes includes an insertion hole disposed at a position corresponding to an end portion of the nip formation pad to accept two or more projections of the projections arranged in the longitudinal direction of the nip formation pad.
