    • A fixing device and an image forming apparatus having the fixing device are provided. The fixing device includes at least two support members, a belt wound on the support members and supported to be movable in a circumferential direction of the support members, a heating member compressed to the belt, and a heat source heating the heating member. A recording medium electrostatically carrying a toner image passes through a fixing nip section formed between the belt and the heating member, thereby heating and fixing the toner image onto the recording medium. Among suspended portions of the belt suspended between the support members, a first suspended portion is in a tensile state, and the second suspended portion is in a non-tensile state. The heating member contacts the outside of the tensile suspended portion to form the fixing nip section.
    • 提供具有定影装置的定影装置和图像形成装置。 固定装置包括至少两个支撑构件,缠绕在支撑构件上并被支撑成可沿着支撑构件的圆周方向移动的带,被压缩到带的加热构件和加热构件的热源。 静电携带调色剂图像的记录介质通过形成在带和加热构件之间的定影夹持区,从而将调色剂图像加热并固定到记录介质上。 在悬挂在支撑构件之间的带的悬挂部分中,第一悬挂部分处于拉伸状态,并且第二悬挂部分处于非拉伸状态。 加热构件接触拉伸悬挂部分的外侧以形成定影夹持区段。

    • An image forming apparatus, including toner image agitating units installed between transfer locations and charging locations of a plurality of image forming portions disposed on a transfer carrier belt, reducing adhesion of residual toner to photosensitive conductors. Toner agitating intensities by the toner image agitating units increase in a direction in which the transfer carrier belt transfers paper. Accordingly, a degradation of the quality of an image due to the residual toner is substantially prevented, leading to an improvement in the printing quality. Also, due to adequate distribution of loads upon the photosensitive conductors, the manufacturing costs and life spans of the photosensitive conductors may be reasonably controlled while keeping a high quality image.
    • 一种图像形成装置,包括安装在转印位置和设置在转印载体带上的多个图像形成部分的充电位置之间的调色剂图像搅拌单元,减少了残留调色剂对感光体的粘附。 调色剂图像搅拌单元的调色剂搅拌强度在转印带传送纸的方向上增加。 因此,基本上防止了由于残留调色剂引起的图像质量的劣化,从而提高了打印质量。 此外,由于光敏导体上的负载分配足够,可以在保持高质量图像的同时合理地控制感光导体的制造成本和寿命。
