摘要： A drying device includes a first heater, a second heater, a conveyance path, and an infrared heater. The first heater contacts and heats a medium on which liquid is applied. The second heater contacts and heats the medium. The second heater contacts the medium at a distance longer than a distance at which the first heater contacts the medium. The conveyance path of the medium includes a first conveyance-path portion and a second conveyance-path portion. The medium is conveyed while contacting the first heater in the first conveyance-path portion. The first conveyance-path portion is disposed upstream from the second heater in a direction of conveyance of the medium. The second conveyance-path portion is disposed downstream from the second heater in the direction of conveyance of the medium. The infrared heater is disposed in the second conveyance-path portion, to irradiate an infrared ray to the medium.

摘要： A drying device includes a drier, a gas circulator, and a concentration adjuster. The drier warms a liquid composition on a drying target object. The gas circulator circulates a gas containing a volatile component of an organic solvent warmed and volatilized by the drier to reuse the gas for drying. The concentration adjuster adjusts a concentration of the volatile component reused.

摘要： A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.
摘要翻译： 定影装置包括待加热的固定构件和用于与定影构件压力接触的压力接触构件。 定影装置通过形成在固定构件和压力施加构件之间的辊隙引导并传送记录构件，使得承载在记录构件上的调色剂图像与定影构件接触以便在热和压力下固定。 定影装置被构造成当只有尖端边缘从辊隙离开时，将记录构件的尖端边缘朝向压力施加构件引导穿过从辊隙的下游端到上游端部拉出的虚拟线性延伸线。 固定构件侧分离装置可以从定影装置的表面分离设置，以便将从辊隙出来的记录构件分开。 在辊隙的下游端和固定件侧分离装置的末端之间形成的间隙被设定为小于前端边缘的宽度。
