摘要： To improve image quality upon preventing abrasion traces from strongly forming on a surface of a fusing member, an invented fusing device has a pressure member, a fusing member movably arranged as faced with the pressure member, and a contact element arranged in contact with an outer circumferential surface of the fusing member, with the surface roughness of the fusing member of 1.0 to 4.0 [μm]. When the fusing member is moved in contact with the contact element, the contact element rubs a surface of the fusing member, but in the fusing member, the portion in contact with the contact element and the portion not in contact with the contact element become about equal in the surface roughness with the above surface roughness.

摘要： An electrophotographic image recording apparatus incorporates a fixing unit in which a toner image deposited on a print medium is fused by heat under pressure. The fixing unit includes a fixing member and a separator plate. The fixing member is in pressure contact with a pressure member. The separator plate that is disposed close to the fixing member and has a longitudinal portion extending in a direction transverse to a transport path of the print medium. The separator plate has a mid portion of the longitudinal portion. The mid portion has resiliency to extend away from the transport path and a guide member that pushes the mid portion of the separator plate to maintain the entire longitudinal portion flat so that mid portion is prevented from extending away from the transport path.

摘要： When the surface temperature of a heating roller exceeds a predetermined temperature, bearings that rotatably support the heating roller melt. Thus, a pressuring roller causes the heating roller to move toward a temperature detecting device. Thus, the heating roller comes in contact with the temperature detecting device. Consequently, when a defect takes place, the warm-up time after the temperature detecting device works until the power to the heater is shut off can be reduced. In addition or in the alternative, an electrode plate has edges electrically contacting and connecting the heater in the heating roller and a power supply. As the heating roller moves, electrical contact between the heater and the electrode plate is broken and the power from the power supply to the heater is disconnected. As a result, an electrophotographic printing apparatus can be prevented from getting defective, thereby improving the reliability thereof.
摘要翻译：当加热辊的表面温度超过预定温度时，可旋转地支撑加热辊的轴承熔化。因此，加压辊使加热辊向温度检测装置移动。因此，加热辊与温度检测装置接触。因此，当发生缺陷时，可以减少在温度检测装置工作之后的预热时间，直到关闭加热器的电源为止。另外或在替代方案中，电极板具有电接触和连接加热辊中的加热器和电源的边缘。当加热辊移动时，加热器和电极板之间的电接触被破坏，并且从电源到加热器的电力被断开。结果，可以防止电子照相打印装置的缺陷，从而提高其可靠性。

摘要： A medium thickness detecting apparatus detects the thickness of a recording medium. A displacement section is disposed in a transport path through which a recording medium passes. When the recording medium passes the displacement section, the displacement section displaces in a direction substantially normal to the surface of a recording medium. An amplifying section amplifies a displacement of the displacement section by a predetermined factor. A thickness determining section outputs a signal representative of an amplified value of the displacement. The displacement section may be one of two rollers between which the recording medium passes, and displaces upward when the recording medium passes between the two rollers. Alternatively, the displacement section my be positioned to sit on a stage provided in the transport path such that the displacement section is pushed away from the stage when the recording medium passes between the displacement section and the surface.
