    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: Curling of edges of recording paper in a toner-image fixing device is prevented. A temperature control unit controls the operation of a heater-lamp for heating a fixing roller in such a way that the fixing roller temperature when the front edge of recording paper enters into the fixing device is lower than the fixing roller temperature when a tail end of the recording paper enters.

    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: 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: 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.
