摘要： A heat-resistant sheet is provided between a fusing roller and a pressing member made of a resilient material. The heat-resistant sheet is composed of a glass fiber substrate coated with or impregnating a fluororesin having good mold lubrication and heat-resistance, such as PFA and PTFE. A paper having a pre-fused toner image is carried through a section between the fusing roller and heat-resistant sheet. Accordingly, wear or separation of the heat-resistant sheet caused by friction with the fusing roller can be prevented, thereby improving durability of the heat-resistant sheet.

摘要： A fixing device has a fixing roller, a press member disposed in a press state in an axial direction of the fixing roller on the periphery surface thereof, and a transport guide for guiding transport of paper. The press member is formed so that the free height of a guide part on an upstream side with respect to the transport direction of the paper is lower than that of the pressure portion pressed to the fixing roller via a heat resistant sheet. Therefore, since the apparent elasticity hardness of the pressure portion can be made relatively small, the nip width formed by the fixing roller and the press member can be made large. Consequently, the fixing of toner to the paper is improved. Even when, for example, a thin sheet of paper or an envelope is used as the paper, the fixing device can suppress the occurrence of paper jam, such as paper lodging, and improper paper insertion.
摘要翻译： 定影装置具有定影辊，在周向表面上沿着定影辊的轴向按压状态设置的按压部件，以及用于引导纸张的输送的输送引导件。 按压部件形成为使得相对于纸张传送方向的上游侧的引导部分的自由高度低于通过耐热片材压在定影辊上的压力部分的自由高度。 因此，由于能够使压力部的表观弹性硬度相对较小，所以能够使由定影辊和压力部件形成的辊隙宽度大。 因此，改善了调色剂到纸张的固定。 即使例如使用薄片纸或信封作为纸，定影装置也可以抑制诸如纸张倒伏和不正确的纸张插入等卡纸的发生。

摘要： The inner surface of a fixing roller is divided into two areas in the lengthwise direction thereof. In one of the areas where the increase rate of the surface temperature of the fixing roller is small, and improper fixing to recording paper is likely to occur, black heat resistant coating is applied to the inner surface of the fixing roller to improve heat absorption. In addition, in the other area where the surface state of the inner surface of the fixing roller is non-uniform, and heat absorption is not stable, transparent heat resistant coating is applied to the inner surface of the fixing roller to stabilize the heat absorption. It is attempted in this manner to make uniform the temperature of the fixing roller in the lengthwise direction thereof and thus to make uniform the fixing in the whole paper-passing area.

摘要： Energy saving in a fixing unit having a low heat capacity is achieved by reducing a loss of heat transferring from a temperature sensing element to temperature sensing unit and by improving response of the safety device. A heat-insulating member is formed to cover a temperature fuse being a temperature sensing element and a heat-conductive filler or heat-conductive elastic member is formed between the temperature fuse and a sliding sheet. A temperature sensing means having the temperature sensing element abuts on a fixing roller through a sliding sheet interposed therebetween. A contacting portion of the temperature sensing means with the heat-insulating member and the filler or elastic member has a curved contacting surface fitting a cylindrical surface of the fixing roller. The heat-insulating member has a groove or a slit for engaging with a protrusion of the temperature sensing element to be secured to the heat-insulating member.

摘要： In a fixing device, a sheet of paper carrying an image formed with pre-fixed toner is transported to a fixing nip region in which (1) a fixing roller heated by a heating roller outside of the fixing roller and (2) a pressure roller come into contact, so that the toner is melted and fixed on the sheet of paper. The heating roller is controlled so that a surface portion of the fixing roller in the vicinity of an exit of the fixing nip region constantly has a set temperature during the transport of the sheet of paper through the fixing nip region. By thus arranging a fixing device, the resultant fixing device features a short warm-up period, high thermal efficiency and uniform temperature distribution, capability of fixing color toner without application of oil, durability and safety, a simple structure and a low manufacturing cost, no curling of paper after fixation, and applicability to high-speed printing.
