Abstract: The fixing device includes a heated rotating body, a pressure rotating body, a heating unit configured to heat the heated rotating body, a separation claw, and a gap rolling member. The pressure rotating body is pressed against the heated rotating body to form a fixing nip portion. The separation claw separates the recording medium from the heated rotating body or the pressure rotating body. The gap rolling member is rotatably supported by the separation claw and abuts against an outer peripheral surface of the heated rotating body or the pressure rotating body to define a gap between the heated rotating body or the pressure rotating body and a tip portion of the separation claw. The separation claw has a conveyance surface facing the recording medium passing through the fixing nip portion, and a part of an outer peripheral surface of the gap rolling member protrudes from the conveyance surface.

Abstract: A fixing device includes a heating body, a pressurizing body, a separation claw, and a supporting member. The heating body heats a medium where a toner image is formed while the heating body rotates around a shaft. The pressurizing body forms a nip with the heating body and applies pressure to the medium that passes through the nip while the pressurizing body rotates around a shaft. The separation claw includes a protrusion that contacts the medium after having passed through the nip and separates the medium from the heating body. The supporting member supports the separation claw in state of causing the separation claw into contact with the heating body. The supporting member supports the separation claw while the supporting member causes the separation claw to slide in a direction separating from the heating body when the medium is brought into contact with the protrusion to press the protrusion.

Abstract: In a fixing device, on a receiving surface of a separating plate provided at a downstream side of a nip part formed between the fixing roller and the pressing roller, a catch part is formed in an edge part facing the nip part. When a direction of a sheet ejected from the nip part comes close to the fixing roller, a front end part of the sheet is caught by the catch part, and the sheet is largely bent or leaps up. A position detector detects the bending or leaping up of the sheet and recognizes that the direction of the sheet ejected from the nip part comes close to the fixing roller. The controller decreases force for pressing the fixing roller and the pressing roller or a fixing temperature, whereby the direction of the sheet ejected from the nip part is deviated from the fixing roller.

Abstract: An image forming apparatus includes a fixing device, a conveyance rollers pair, a curved path and a first guide roller. The fixing device fixes a toner image on a sheet. The conveyance rollers pair conveys the sheet on which the toner image is fixed by the fixing device. The curved path is provided between the fixing device and the conveyance rollers pair, and the sheet is conveyed along the curved path with a toner image fixed surface facing an inner peripheral side of the curved path. The first guide roller is shiftable between a guide position protruding in the curved path from the inner peripheral side and the inner peripheral side. When the sheet is conveyed along the curved path, the first guide roller is pushed by the sheet while rotating following the sheet and then is shifted from the guide position to the inner peripheral side.

Abstract: A curl correcting device includes a pair of fixed guides and a change-over guide. The pair of fixed guides composes a curved part of a conveyance path. The change-over guide is provided to be contactable with a sheet from a radial outer side of the curved part. An outer guide includes a pair of side pressing parts and a bulge part. The pair of side pressing parts is formed at both ends in a width direction. The bulge part is formed between the pair of side pressing parts so as to bulge toward the radial outer side of the curved part. The change-over guide is configured to move to a first correcting position when the sheet curled along the conveyance direction is conveyed through the conveyance path and to move to a second correcting position when the sheet curled along the width direction is conveyed through the conveyance path.

Abstract: An image forming apparatus has a fusing device in which a recording medium carrying an unfused toner image is nipped at a fusing nip formed between a heated member and a pressing member to fuse and fix the unfused toner image to the recording medium, and an exhaust duct unit through which air around the fusing device is expelled outside. The exhaust duct unit allows a choice between a first exhaust path through which outside air sucked into the image forming apparatus is passed through a space around the fusing device and is then expelled out of the image forming apparatus, and a second exhaust path in which a filter for collecting particles contained in an air stream is arranged and through which the air around the fusing device is passed through the filter and is then expelled out of the image forming apparatus.
