    • An image forming apparatus carries out an image processing with respect to a sheet size and image information based on a print request to obtain a write image on a photoreceptor. On the basis of a printing ratio of the write image, the apparatus predicts occurrence of an image elongation. If the apparatus predicts that the image elongation occurs, the apparatus calculates a bending amount of a bended portion based on the difference between peripheral velocities of a photoreceptor and the idle roller, and the apparatus variably controls the peripheral velocity of an idle roller so that the bending amount is adjusted so as not to cause a slip phenomenon. It is possible to avoid the occurrence of a phenomenon of slipping of a sheet with respect to the photoreceptor without lowering image quality, and to surely secure a blank space formed at a rear edge portion of the sheet.
    • 图像形成装置基于打印请求对纸张尺寸和图像信息进行图像处理,以在感光体上获得写入图像。 基于写入图像的打印率,该装置预测图像伸长的发生。 如果该装置预测图像伸长发生,则该装置基于感光体的周向速度与空转辊之间的差异来计算弯曲部分的弯曲量,并且该装置可变地控制空转辊的圆周速度,使得 调整弯曲量,不会产生滑动现象。 可以避免在不降低图像质量的情况下发生片材相对于感光体的滑动现象,并且可靠地确保形成在片材的后边缘部分处的坯料空间。

    • Support structures for containing and supporting components forming a digital copier are configured with square pipes and are provided separately in association with a plurality of units of the digital copier. The effect of distortion is eliminated when the support structures are joined to maintain positional accuracy. Square pipes are combined to form each of a first support structure for containing and supporting various components forming the digital copier, for example, an image forming process portion and a fixing portion and a second support structure for containing and supporting various components to be incorporated therein as needed, for example, a sheet supplying portion. To combine the first and second support structures, square pipes and square pipes orthogonal to each other are joined in the regions of joining surfaces. This makes it possible to prevent, for example, distortion and twisting between the supporting structures.

    • An image transfer roller cleaning system for operation in conjunction with a retractable image transfer roller in an image forming apparatus. A transfer belt extends through a gap between the transfer areas of a group of photoreceptor drums and corresponding image transfer rollers from an upstream side to a downstream side. The photoreceptor drums are arranged in parallel to one another. The transfer rollers urge the transfer belt into engagement with the respective transfer areas of the photoreceptor drums during the transport of a printing medium through the gap. A cleaning brush located upstream from the gap acts to clean the inner side of the belt prior to its entry into the gap. Cleaning blades also clean the outer surfaces of the transfer rollers when predetermined transfer voltages are not being applied thereto. In addition, the cleaning system may include features such as checking sensors and/or circuits for monitoring purposes. Applied voltage variation controllers for optimizing the quantity of toner carried by the photoreceptor drums also may be included. Further, image formation prohibiting controllers for preventing the formation of an image in those cases where the portions of the system checked by the checking devices register signal readings outside of predetermined ranges may be included. In addition, apparatus for moving the transfer rollers and/or the transfer belt wholly, or partially, out of their normal image transfer positions for cleaning purposes may be included.

    • A request condition managing table is provided to a request-sender digital copying machine. For example, when the request-sender digital copying machine is reset to a predetermined condition, the PCU of the request-sender digital copying machine outputs a clear signal to a request-receiver digital copying machine through a transmitting apparatus, so that the image data stored therein on behalf of the request-sender digital copying machine are cleared. Alternatively, the operator can erase such image data manually by checking the request condition managing table. In this manner, when the image data read by the request-sender image forming apparatus and stored temporarily in the request-receiver image forming apparatus become useless, the request-sender image forming apparatus so notifies the request-receiver image forming apparatus and directs the same to erase the image data, thereby preventing the request-receiver image forming apparatus from storing useless image data over a long period.
    • 向请求发送者数字复印机提供请求条件管理表。 例如,当请求发送者数字复印机被复位到预定条件时,请求发送者数字复制机的PCU通过发送装置向请求接收机数字复印机输出清除信号,使得图像数据 存储在其中的代表请求发送者数字复印机被清除。 或者,操作者可以通过检查请求条件管理表来手动擦除这样的图像数据。 以这种方式,当请求发送者图像形成装置读取并存储在请求 - 接收图像形成装置中的图像数据变得无用时,请求 - 发送者图像形成装置通知请求 - 接收者图像形成装置并指示 相同地擦除图像数据,从而防止请求 - 接收器图像形成装置长时间存储无用的图像数据。
