摘要： A charging device, an image forming apparatus including the charging device, an image carrier unit including the charging device and a charging roller, which faces a body to be charged and is applied with a voltage, are disclosed. The charging roller includes a metallic core and an elastic member covering the core. Films are respectively wrapped around and adhered to the opposite end portions of the elastic member. Springs press the charging roller toward a body to be charged, causing the elastic member to deform due to compression. The maximum deformation of the films, which deform along the outer periphery of the elastic member, is selected to be smaller than the thickness of each film in the radial direction of the charge roller. A gap is therefore formed between the elastic member and the body to be charged. This prevents the portion of the elastic member, which corresponds to an image forming region, other than opposite end portions from contacting the surface of the body to be charged.

摘要： To prevent deterioration of charge performance, which is caused by wear of a gap control member that keeps a charge roller into non-contact with the image carrier, the charge roller is brought into contact with a surface of a photosensitive drum via a pair of tape members as the gap control member that contacts with a coat and non-charge portion of the photosensitive drum. A gap G can be formed between an effective charge width portion of the charge roller and the surface of the photosensitive drum.

摘要： An image forming apparatus including an image bearing member, a charging member, and a measuring member. The image forming member is configured to bear an image. The charging member is configured to charge a surface of the image bearing member when a direct current bias voltage is added to at least an alternating bias voltage which is applied to the charging member, and has a frequency fc of the alternating bias voltage. The measuring member is configured to measure a potential of the surface of the image bearing member, and has a drive frequency fvsen. The relationship of the frequency fc and the drive frequency fvsen is expressed as fc≠fvsen×n and fc×n≠fvsen.

摘要： An image forming apparatus of the present invention includes a plurality of image carriers sequentially arranged in a direction of paper conveyance. Developing devices each form a toner image of particular color on one image carrier associated therewith. Cleaning devices each remove residual toner left on the surface of the associated image carriers after the transfer of the toner image to the recording medium. A toner recycling device is provided between the cleaning device located at the most upstream position in the direction of paper conveyance and the developing device associated therewith, but not provided between the cleaning device located at the most downstream position the developing device assigned therewith. With this configuration, the apparatus obviates troubles ascribable to the mixture of toner of different colors occurring in the most downstream developing device. In addition, at a time other than the time of transferring toner images from the image carriers to the recording medium, a controller activates a mixed toner consumption mode such that any one of the developing devices, other than a developing device located at most upstream position in the direction of conveyance of the recording medium, is caused to deposit toner on the image carrier which is than transferred to a recording medium carrier and then cleaned to remove the toner.
摘要翻译：本发明的图像形成装置包括顺序地沿着纸张传送方向布置的多个图像载体。显影装置各自在与其相关联的一个图像载体上形成特定颜色的调色剂图像。在将调色剂图像转印到记录介质之后，清洁装置每次去除留在相关联的图像载体表面上的剩余调色剂。调色剂回收装置设置在位于纸张传送方向上的最上游位置处的清洁装置与与其相关联的显影装置之间，但不设置在位于最下游位置处的清洁装置之间。利用这种结构，该装置避免了由于最下游显影装置中出现的不同颜色的调色剂的混合引起的麻烦。此外，除了将调色剂图像从图像载体转印到记录介质的时间之外的时间，控制器启动混合调色剂消耗模式，使得除显影装置之外的任何一个显影装置位于最上游位置在记录介质的传送方向上，将调色剂沉积在转印到记录介质载体上的图像载体上，然后清洁以除去调色剂。
