摘要： A belt fixing unit, an image forming apparatus, and a toner material are disclosed capable of obviating undesirable fixing belt deformation and low image quality. The belt fixing unit includes a fixing roller, a heating roller, a fixing belt, and a pressing roller in contact with the fixing roller to form a fixing nip having the fixing belt intervening there between, the fixing belt including at least a base member formed of a heat-resisting resin having a thickness of 90 μm or smaller and acted upon by a tensile force of 0.49 N/mm or less. The toner is a low-melting point toner formed by subjecting a toner preparatory solution containing at least a prepolymer having a functional group containing a nitrogen atom, a polyester, a colorant and a releasing agent dispersed in an organic solvent to extension and/or crosslinking reactions in an aqueous medium.

摘要： An image forming apparatus of the type transferring a toner image from a photoconductive element to a recording medium by way of an intermediate transfer belt is disclosed. Toner images of different colors are sequentially transferred from the photoconductive element to the intermediate transfer belt one above the other, forming a full-color image. When the full-color image is to be transferred from the intermediate transfer belt to a paper or similar recording medium, a secondary transfer belt is brought into contact with the portion of the intermediate transfer belt contacting a secondary transfer roller. As a result, the secondary transfer belt deforms complementarily to the shape of the secondary transfer roller, forming a nip between it and the intermediate transfer belt. In this condition, the secondary transfer belt contacts the intermediate transfer belt evenly and prevents an excessive pressure from acting locally on the toner image existing on the intermediate transfer belt.

摘要翻译： 公开了一种通过中间转印带将调色剂图像从感光元件转印到记录介质上的图像形成装置。 不同颜色的调色剂图像从感光元件依次转印到中间转印带上，形成全色图像。 当将全色图像从中间转印带传送到纸或类似记录介质时，二次转印带与接触二次转印辊的中间转印带的部分接触。 结果，二次转印带与二次转印辊的形状互补地变形，在其与中间转印带之间形成辊隙。 在这种情况下，二次转印带均匀地接触中间转印带，并防止过度的压力局部地作用在中间转印带上存在的调色剂图像上。
