摘要： A color image forming machine such as a copier or a printer for producing a toner image, corresponding to an original image, on a recording sheet. The color image forming machine has a photoreceptor for forming the toner image on its surface; a transferrer for transferring the toner image from the photoreceptor to the recording sheet; and a fixer for fixing the toner image on the recording sheet. The fixer includes (1) an endless heat belt which is supported by a heat roller and a separation roller; and (2) an endless conveyance belt which is supported by a pressure roller and another separation roller; in which the endless heat belt and the endless conveyance belt are partially pressed together by the first pair which are inclined relative to one another, and the second pair so that a nip region is created between the first pair of rollers and the second pair of rollers. The endless heat belt and the endless conveyance belt have a glossy surface. The fixer conveys the recording sheet upwards in the apparatus when the fixer fixes the toner image on the recording sheet.

摘要： Image forming apparatus provided with a process cartridge including at least a belt-shaped image carrier. A protective cover automatically covers a transfer section of the image carrier installed in the process cartridge, in response to a traveling motion of the process cartridge from a first position in which an image can be formed, to a second position in which the process cartridge can be attached to or detached from the apparatus. The protective cover also automatically exposes the transfer section of the image carrier in response to the input of a power source to the apparatus, or the input of an image forming signal for forming a latent image on the image carrier, or the process of mounting of the process cartridge to the apparatus.

摘要： An image forming apparatus includes a process cartridge that incorporates a photoreceptor and a plurality of developing devices. The process cartridge is provided with a first driving shaft to drive the photoreceptor and a second driving shaft to independently drive the developing devices. When the process cartridge is mounted in the image forming apparatus which includes spaced apart first and second gears, the first and second driving shafts are coupled separately with the spaced apart first and second gears so that driving forces are separately transmitted to the first and second driving shafts. A flywheel is mounted on a third driving shaft that is coupled with the first driving shaft to drive the photoreceptor. Since the developing devices are constructed to receive a large number of different possible loads, the developers are placed in a condition where vibrations are created easily by the driving of the various possible loads. The driving of the photoreceptor is arranged to be independent of the driving of the developing devices so that vibrations generated by the driving of the developing devices are not transmitted to the photoreceptor. Furthermore, the flywheel is provided on the third driving shaft, and a third gear is mounted on the third driving shaft. Since the third gear is coupled with the first driving shaft to drive the photoreceptor, the rotation of the photoreceptor will be smoothed out by the presence of the flywheel.
摘要翻译： 图像形成装置包括具有感光体和多个显影装置的处理盒。 处理盒设置有驱动感光体的第一驱动轴和独立地驱动显影装置的第二驱动轴。 当处理盒安装在包括间隔开的第一和第二齿轮的图像形成装置中时，第一和第二驱动轴与间隔开的第一和第二齿轮分开地联接，使得驱动力被分开地传递到第一和第二驱动 轴。 飞轮安装在与第一驱动轴联接以驱动感光体的第三驱动轴上。 由于显影装置被构造成接收大量不同的可能负载，所以显影剂被置于通过驱动各种可能的负载容易产生振动的状态。 感光体的驱动被设置为独立于显影装置的驱动，使得由显影装置的驱动产生的振动不会传递到感光体。 此外，飞轮设置在第三驱动轴上，第三齿轮安装在第三驱动轴上。 由于第三齿轮与第一驱动轴联接以驱动感光体，因此感光体的旋转将通过飞轮的存在而被平滑。
