摘要： A fixing device has a presser member, a slide member and a pressure belt. Both ends of the presser member are positioned outside both ends of the slide member. Both ends of the slide member are positioned outside both ends of the pressure belt. Thereby, the slide member and the pressure belt are improved in service life, so that the fixing device as a whole is improved in service life.

摘要： A fixing device of the present invention includes a holding frame placed along a fixed pressing member. The holding frame includes a groove section having a recessed cross section and extending along the width direction of a sheet. The fixed pressing member is housed in the groove section. The fixed pressing member is pressed toward the rotor so that the rotor and the fixed pressing member are put in pressure contact with each other. A first engaging element is provided in a predetermined position on the bottom face of the groove section of the holding frame. A second engaging element which engages with the first engaging element is provided in a position on the fixed pressing member which corresponds to the positions of the first engaging element on the holding frame.

摘要： A fixing device has a presser member, a heating roller and a pressure belt. An overall length of the presser member is longer than an overall length of a rubber layer of the heating roller. Both ends of the presser member are positioned outside both ends of the rubber layer of the heating roller. An overall length of the presser member is longer than an overall length of the pressure belt. Both ends of the presser member are positioned outside both ends of the pressure belt. Thereby, the heating roller and the pressure belt are improved in service life, so that the fixing device as a whole is improved in service life.

摘要： Fixing belt is brought into pressure-contact with the surface of fixing roller such that fixing belt rotates according to rotation of fixing roller, thereby forming, between fixing belt and fixing roller, fixing nip portion through which recording sheets pass. A pressing area of an opposing surface of pressing member contacting the surface of fixing roller via fixing belt is smaller in each end portion of the opposing surface in the axis direction of fixing roller than in a central portion of the opposing surface in the axis direction of fixing roller. This makes speed of conveying recording sheets faster in each edge portion in the width direction perpendicular to a recording sheet conveyance direction than in a central portion in the width direction. Thus, creases of recording sheets can be prevented while a recording sheet passes through fixing nip portion between fixing roller and fixing belt mutually brought into pressure-contact.

摘要翻译： 定影带与定影辊的表面压力接触，使得定影带根据定影辊的旋转而旋转，从而在定影带和定影辊之间形成定影夹持部分，通过该定影辊隙部分。 在定影辊的轴向上的相对表面的每个端部的相对表面的相对表面的相对表面的按压区域在定影辊的轴线方向上的相对表面的中心部分比在定影辊的轴向方向上的中心部分小 定影辊。 这使得在垂直于记录纸张传送方向的宽度方向上的每个边缘部分中传送记录纸张的速度比宽度方向上的中心部分快。 因此，当记录纸通过定影辊和相互压力接触的定影带之间的定影辊隙部分时，可以防止记录纸的折痕。
