    • A manufacturing method for manufacturing a bellows having pleat walls with S-shaped profiles comprises a primary forming process for forming a formed bellows, a pressing process for compressing the formed bellows in the axial direction, and a stretching process for pulling the compressed bellows in the axial direction, thereby obtaining desired pitches and free length. After the stretching process is carried out, the bellows is subjected to an annealing and ageing heat-treatment process. An apparatus for manufacturing the bellows comprises a pair of molds that have their respective forming surfaces in shapes corresponding individually to the pleat walls. The die is slightly retreated away from the pleat walls just before the dies open in the diametrical direction after the pleat walls are formed.
    • 用于制造具有S形轮廓的褶皱壁的波纹管的制造方法包括用于形成成形波纹管的初级成形工艺,用于沿轴向压缩所形成的波纹管的压制工艺,以及用于将压缩波纹管拉在 轴向,从而获得期望的间距和自由长度。 在进行拉伸处理之后,对波纹管进行退火和时效热处理。 一种用于制造波纹管的装置包括一对模具,它们各自的形状表面的形状分别对应于褶皱壁。 在褶皱壁形成之后,模具在刚好在直径方向上打开之前的褶皱壁稍微退缩。

    • Image forming equipment, which includes a developing device for supplying toners to the surface of a photosensitive member and developing a latent image on the surface of the photosensitive member to thereby form a toner image; a cleaning device for removing and collecting residual toners adhered to the surface of the photosensitive member after the toner image formed by the developing device is transferred to paper; a toner delivery device interposed in a closed loop between the developing device and cleaning device for delivering part of the surplus toners that have not been used for development in the development device to the cleaning device and for delivering the residual toners collected by the cleaning device to the developing device; and a toner tank for supplying toners to a toner delivery path R of the toner delivery device, is provided. In the image forming equipment, by providing a detection system for detecting the depletion of the toners with respect to the toner delivery path, the residual quantity of toners can be detected positively without increasing the size of the developing device.
    • 图像形成设备,其包括用于向感光构件的表面供应调色剂并在感光构件的表面上显影潜像从而形成调色剂图像的显影装置; 用于去除和收集由显影装置形成的调色剂图像之后粘附到感光构件表面的残留调色剂的清洁装置被转印到纸上; 调色剂输送装置,介于显影装置和清洁装置之间的闭环中,用于将未被用于显影装置中的显影的部分剩余调色剂输送到清洁装置,并将由清洁装置收集的残留调色剂输送到 显影装置; 以及用于向调色剂输送装置的调色剂输送路径R供给调色剂的调色剂罐。 在图像形成设备中,通过提供用于检测调色剂相对于调色剂输送路径的消耗的检测系统,可以积极地检测调色剂的剩余量而不增加显影装置的尺寸。
