摘要： In an image forming apparatus of the present invention, an idle roller once stops rotating when a front edge of a sheet conveyed reaches the idle roller. The idle roller restarts rotating at such a timing that a front edge of a toner image on a photoreceptor and a front edge of an image writing position on the sheet are aligned with each other. Then, even if a rear edge of the sheet is still in the idle roller, the idle roller stops rotating when the front edge of the sheet is sandwiched between a transfer roller and the photoreceptor. By carrying out such operations, it is possible to avoid by a very simple way an occurrence of a slip phenomenon that is a phenomenon of slipping of the sheet with respect to the photoreceptor while suppressing a reduction in image quality as much as possible. In addition, it is also possible to surely secure a blank space formed at a rear edge portion of the sheet.

摘要： 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.
摘要翻译：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。

摘要： A belt conveyor member includes an endless belt and a cleaning blade. The cleaning blade is configured to remove residual toner remaining on a surface of the endless belt which is processed into a smooth surface. The endless belt has a first region and a second region. The first region is a region in contact with the cleaning blade which is located outside a region for a recording sheet of a maximum usable width to pass therethrough. The second region is located outside the first region. A contact surface between the cleaning blade and the first region is in a rough condition free from intimate contact.

摘要： A secondary transfer unit stretches a transfer belt in an endless form over a driving roller, a driven roller, a transfer roller, an auxiliary roller, and a support roller therebetween. The transfer belt moves, by rotation of the driving roller, along a circulation path which passes through a transfer position. The transfer roller and the auxiliary roller press the transfer belt from the inner peripheral surface of the transfer belt toward an intermediate transfer belt in the transfer position. The transfer belt has an outer peripheral surface thereof which is pressed against the intermediate transfer belt and is roughened so that the surface roughness of the outer peripheral surface becomes 6 μm to 10 μm.

摘要： A transfer device includes a transfer belt, a transfer roller and a tension roller over which the transfer belt is passed in a tensioned condition and which is made to be in an electrically floated state; it also includes a guide member that is installed in the vicinity of the tension roller. A control section, in transfer processing, controls a first switch so that the guide member is in a grounded state while controlling a second switch so that an electric current being caused to flow to the transfer roller becomes a first electric current; and in cleaning processing, controls the first switch so that the guide member is in an electrically floated state while controlling the second switch so that an electric current being caused to flow to the transfer roller becomes a second electric current.

摘要： An image forming apparatus is provided. When a user inputs a print request, life count values stored in a life management section are read out. A table of correlation between the life count values and a rotating speed of a driving roller is looked up, a rotating speed of the driving roller corresponding to the life count values read out is determined at which the driving roller is set to rotate. With the driving roller rotating at the set rotating speed, a printing process is performed so that a transfer belt turns at a constant running speed. Following the printing process, the life count values are updated based on the latest total number of printed copies and the latest revolving speed of the transfer belt.

摘要： A feed roller assembly includes a shaft, a plurality of rollers, and a plurality of covers. The rollers are fixed to the shaft at intervals along it. The covers are positioned at both ends of the rollers and surround the shaft, without being fixed to it. Paper dust falls from the outer cylindrical surfaces of the rollers and accumulates on the covers, without coming into direct contact with the cylindrical surface of the shaft. Because the covers are not fixed to the cylindrical surface of the shaft, they rotate at a lower speed than the shaft.
