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 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.
摘要翻译：第一焊盘具有沿X方向延伸的第一压区形成表面。形成在第一辊隙形成表面的端部与XZ平面之间的角度小于在第一辊隙形成表面的中心部分和 XZ平面，其中XZ平面形成在第一辊隙形成表面的下游侧。因此，提供一种定影装置，当定影装置将调色剂固定在记录材料上并传送时，可以抑制记录材料上的皱纹的产生。

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。
