摘要： A conveying device includes a rotator, a drier, and a conveyance direction changer. The rotator winds a web-shaped recording medium around a predetermined region of an outer peripheral surface of the rotator with one side of the web-shaped recording medium facing outward and conveys the recording medium with rotation. The drier is disposed downstream from the rotator in a direction of conveyance of the recording medium, to dry and convey the recording medium. The conveyance direction changer is disposed on a conveyance path of the recording medium between the rotator and the drier. The conveyance direction changer has an outer peripheral surface that includes an opposed region opposed to the one side of the recording medium. The opposed region has openings to blow gas toward the one side of the recording medium. The rotator and the drier are disposed at positions not overlapping with each other in a plan view.

摘要： A recording medium heating device that can heat and dry a continuous recording medium, includes multiple heating rollers, including respective heaters, disposed on a conveying path of the recording medium; and a controller to control the heaters of the heating rollers. In a starting period during which the recording medium heating device is started, the controller sets temperatures of the heaters to starting temperatures where a temperature of a heating roller positioned closest to an exit side of the conveying path is lower than a temperature of a heating roller positioned away from the exit side of the conveying path.

摘要： A fixing device that allows simple and safe replacement of heating rollers. The fixing device includes a first lamp holder provided in the inner periphery of a retaining member, and an interlock device for locking and unlocking the first lamp holder and the retaining member. When replacing the heat roller, the interlock between the first lamp cartridge and the retaining member is unlocked to take out the retaining member and the heating roller from the opening of the frame of the image forming apparatus, while leaving the lamp cartridge inside the apparatus.
