摘要： A fixing device is provided, which has a fixing roller and a sheet. A recording paper where a toner image has been transcribed thereon is passed through a nip portion between the fixing roller and the sheet. By pressing and heating, the toner image is fixed on the recording paper. A heating line is wound on a surface opposite to a sheet's surface that is in contact with the fixing roller. By applying a power source to the heating line, the sheet is heated. When the recording paper enters the nip, the cause of the temperature suddenly lowering can be prevented.

摘要： A fixing device for a printing device is provided. The fixing device comprises a fixing unit, heated by a heating source; and a sheet-shaped pressure unit, having an elasticity and in contact with the fixing unit by pressing against the fixing unit. When a recording paper that a toner image has been transcribed thereon passes through a nip portion between the sheet pressing unit and the fixing unit, by pressing and heating, the toner image is fixed on the recording paper. In addition, a surface layer is formed on a surface of the fixing unit, wherein the surface layer comprises a material such as a glass fiber, a graphite, a bronze etc, for increasing a friction coefficient. Further, the surface has a water contact angle greater than or equal to 90°. By setting the friction coefficient of the surface of the fixing roller to a range that the toner does not adhere thereon, the transporting property of the recording paper can be improved.

摘要： A fixing device includes a fixing member, a pressing member, a temperature detector, and a heater. The pressing member contacts an outer circumferential surface of the fixing member to form a fixing nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. The heater heats the fixing member to a predetermined temperature based on a detection result provided by the temperature detector. A circumferential distance A between the temperature detector and the heater along a circumference of the fixing member is defined by the following formula: A≧v×(T1+T2) where v is a circumferential velocity of the fixing member rotating in a predetermined direction of rotation, T1 is a response time of the temperature detector, and T2 is a response time of the heater.
