摘要： An image forming apparatus includes a fixing device in which a width of a slide member is larger than a width of a pressurizing belt while both ends of the slide member are positioned outside of both ends of the pressurizing belt. The above-structured slide member makes it possible to prevent lubricant on the slide member from leaking out of the ends of the slide member and coming around the inner surface of the slide member, and thereby to prevent a pressing member beneath the slide member from swelling, resulting in avoidance of wrinkle generation on recording materials.

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

摘要： A fixing device has a heating roller and a pressure belt, each of which includes a gripping portion at both width-directional ends thereof. The gripping portion corresponds to outside of a range in which a recording material passes. The gripping portion has a friction coefficient greater than that of the surface in the width-directional center portion, which portion corresponds to inside of the range in which the recording material passes. A gripping portion pressurizing part is located inside the gripping portion at both end portions of the pressure belt so as to pressurize the gripping portion of the pressure belt against the gripping portion of the heating roller. This makes it possible to improve frictional resistance between the gripping portions of the heating roller and the pressure belt. Thus, the fixing device allows preventing the conveyance error of the recording material, so that the image quality can be improved, and also the fixing device can be reduced in size and weight.
摘要翻译：定影装置具有加热辊和加压带，每个加压辊和加压带在其两个宽度方向的端部都包括夹持部分。抓握部分对应于记录材料通过的范围的外部。夹持部分的摩擦系数大于宽度方向中心部分的表面的摩擦系数，该部分对应于记录材料通过的范围内部。夹持部分加压部位于压紧带的两端部的夹持部的内侧，从而抵靠加热辊的夹持部对加压带的夹持部进行加压。由此，能够提高加热辊的夹持部和加压带的摩擦阻力。因此，定影装置允许防止记录材料的输送错误，从而可以提高图像质量，并且还可以减小定影装置的尺寸和重量。

摘要： A first pad has a first nip forming surface which extends in a direction X. An angle formed between an end portion of the first nip forming surface and an XZ plane is smaller than an angle formed between a central portion of the first nip forming surface and the XZ plane, where the XZ plane is formed on a downstream side of the first nip forming surface. Thereby, a fixing device is provided which suppresses generation of wrinkles on a recording material when the fixing device fixes toner on the recording material and conveys it.

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。

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.
