摘要： An image-forming apparatus is provided which includes a document reading section for reading image information from a document, and an image-forming section for forming an image on a sheet of paper based upon the image information of the document read by the document reading section. A space section is formed below the document reading section, which accommodates the image-forming section and serves as a discharge section to which the sheet of paper bearing the image formed in the image-forming section is discharged. The space section is surrounded by peripheral walls of an apparatus main body including the image-forming section. The image-forming apparatus further includes a paper post-treatment section that subjects the sheet of paper bearing the image to post-treatments, such as an adjustment process and a stapling process, in a virtually horizontal state, and that is placed between the document reading section and the space section.

摘要： An electrophotographic printing machine is provided with a photoreceptor whereon a transparent electrically conductive layer and a photoconductive layer are successively formed. A visible image is formed on the photoconductive layer by exposing the photoconductive layer while applying a voltage across toner supplied onto the surface of the photoreceptor and the transparent electrically conductive layer. The exposing energy of the exposure unit is set so as to satisfy an equation:V.sub.L .gtoreq.V.sub.D -V.sub.D1,where V.sub.D1 designates the surface electric potential of the photoreceptor that is exerted when the surface of the photoreceptor, originally having a surface electric potential of virtually zero V, passes by the area in contact with the toner; V.sub.D designates the saturation value of the surface electric potential of the photoreceptor that is attained after the surface of the photoreceptor has successively passed by the area in contact with the toner; and V.sub.L designates a lowered surface electric potential of the photoreceptor that is to be reached by an exposure. Therefore, good picture images without being affected by residual images can be obtained.

摘要： An electrophotographic printing machine is provided with a photoreceptor drum including a transparent cylindrical base having a transparent electrically conductive layer and a photoconductive layer laminated in this order on a surface thereof and a dielectric belt in contact with the photoconductive layer. The photosensitive layer is exposed while voltage is being applied across an electrically conductive toner and a transparent electrically conductive layer, thereby forming a toner image on the photosensitive layer. After the toner image on the photosensitive layer is transferred to the dielectric belt which temporarily carries the toner image, the copying material is superimposed on the toner image, and heat and pressure are applied to the toner image respectively from a heater and a pressurizing roller. Since the melted toner is transferred onto the copying material using the adherence of the transfer sheet without using electric Coulomb force, the efficiency in transferring the toner image to the copying material is not affected by the electric surface resistance of the copying material. An image can therefore be formed using the electrically conductive toner even on a copying material of low electric surface resistance such as a normal transfer sheet.
摘要翻译： 电子照相印刷机设置有感光鼓，该感光鼓包括具有透明导电层的透明圆柱形基底和在其表面上依次层叠的光电导层和与光电导层接触的介质带。 感光层在跨导电调色剂和透明导电层施加电压的同时被曝光，从而在感光层上形成调色剂图像。 在感光层上的调色剂图像转印到暂时承载调色剂图像的介质带之后，将复印材料叠加在调色剂图像上，并且从加热器和加压辊分别向调色剂图像施加热和压力。 由于在不使用电库仑力的情况下使用转印片的粘附将熔融的调色剂转印到复印材料上，所以将调色剂图像转印到复印材料的效率不受复印材料的电表面电阻的影响。 因此，即使在诸如普通转印片的低电表面电阻的复印材料上，也可以使用导电调色剂形成图像。

摘要： In one embodiment, when a hot roller is driven to rotate, a driving gear rotates so that a swing gear and a swing cam rotate. Then, a sliding contact edge on the right side of a swing lever that abuts against the circumferential face of the swing cam repeatedly moves up and down, and the swing lever repeatedly rotates clockwise and counterclockwise with a shaft of a pressure release cam as the center. At this time, since only the clockwise rotation of the swing lever is transmitted via a one-way clutch to the shaft of the pressure release cam, the clockwise rotation is intermittently transmitted to the shaft of the pressure release cam. As a result of this, the pressure release cam intermittently rotates clockwise, and the pressure release cam pushes away a roller of a displacement frame, so that the pressure roller separates from the hot roller.
