摘要： A fixing device includes a fixing belt, a nip formation pad, a support, an opposing rotator, a heat source, a housing, an inlet guide, an airflow generator, and an airflow guide. The fixing belt fixes an unfixed image on a recording medium. The nip formation pad is disposed inside a loop of the fixing belt. The support supports the nip formation pad. The opposing rotator abuts on the nip formation pad via the fixing belt. The heat source heats the fixing belt. The housing has an inlet opening to receive the recording medium. The inlet guide is disposed at the inlet opening and guides the recording medium to the fixing nip. The airflow generator generates an airflow in the housing. The airflow guide guides the airflow toward the inlet opening to generate a flow of air in the inlet opening in a direction different from a conveyance direction.

摘要： A fixing device includes a fixing rotator that is rotatable and a heater that heats the fixing rotator. An opposed rotator contacts the fixing rotator to form a fixing nip between the fixing rotator and the opposed rotator. A recording medium bearing an unfixed image is conveyed through the fixing nip. A temperature detector detects a temperature of the fixing rotator. A support supports the temperature detector. An air flow generator generates an air flow directed from a back face to a detecting face of the temperature detector.

摘要： A belt device for an image forming apparatus, includes an endless belt; a first and second support rollers, each including a rotary shaft, that support the belt with tension; a contacted member that contacts the belt; a shaft displacement device to displace any of the rotary shafts of the support rollers; and a main rotary shaft disposed at a side of the rotary shaft of the first support roller moved by the shaft displacement device along a stretching direction of the stretched surface of the endless belt that the contacted member contacts, relative to a contact portion between the endless belt and the contacted member, and at an opposite side of the contacted member in a direction perpendicular to the stretching direction of the endless belt. As the first support roller and the second roller rotate about the main rotary shaft, the endless belt is separated from the contacted member.

摘要： A belt assembly includes a belt, a plurality of support rollers, and a shaft-end retainer. The belt is formed into an endless loop, entrained about and stretched taut between the plurality of support rollers with a rotary shaft. The plurality of support rollers includes a first support roller and a second support roller. The shaft-end retainer including a first retainer and a second retainer is disposed at each end of the rotary shaft of the plurality of support rollers. The first retainer detachably holds an end of the rotary shaft of the first support roller. The second retainer detachably holds an end of the rotary shaft of the second support roller and includes a second-retainer opening from which the end of the rotary shaft of the second roller is detachable from and attachable to the second retainer in a direction perpendicular to the rotary shaft of the second support roller.

摘要： A conveyor system includes a first conveyor belt entrained about a separation roller and a support roller disposed upstream from the separation roller, a second conveyor belt entrained about a first roller disposed at an uppermost stream in a transport direction of a sheet-type medium and a second roller disposed downstream therefrom, a belt alignment device to tilt a rotary shaft of the separation roller to restrict a range of belt mistracking of the first conveyor belt in a width direction thereof within a predetermined range, and a restriction member to restrict an amount of inclination of the rotary shaft such that a hypothetical extended plane, which is a hypothetical extension of the outer circumferential surface of the first conveyor belt between the separation roller and the support roller to a downstream side in the transport direction, does not contact a rotational center axis of the first roller.

摘要： An image forming apparatus includes a transfer unit, a fuser unit, a relative positioning mechanism, and a fine adjustment mechanism. The transfer unit has a transfer nip to transfer an image from an imaging surface to a recording sheet passing therethrough. The fuser unit has a fixing nip to fix the transferred image on the recording sheet passing therethrough. The relative positioning mechanism is configured to position the transfer unit and the fuser unit relative to each other by contacting a contact portion with a flange. The contact portion is formed on one of the transfer unit and the fuser unit. The flange is formed on the other of the transfer unit and the fuser unit. The fine adjustment mechanism is configured to align the transfer nip and the fusing nip relative to each other.
