摘要： An image forming apparatus includes a cleaning member for collecting toner left on an image carrier after image transfer, and then redepositing it on the carrier, so that a developing unit can collect the redeposited toner to reuse it. Even when the frictional charging ability of the cleaning member falls due to aging or varying environment, the charge of the toner left on the image carrier is regulated to preselected polarity before the toner reaches the cleaning member, thereby enhancing a toner collecting efficiency and a toner redepositing efficiency. The charge of the toner redeposited on the image carrier and moved away from the cleaning member is regulated to preselected polarity while being increased, thereby reducing a load to act on the developing unit. The toner is redeposited on the image carrier efficiently without regard to the polarity of the toner collected by the cleaning member. The developing unit is allowed to collect all the toner redeposited on the image carrier, thereby freeing the background of an image from contamination. When the cleaning member collects the toner from the image carrier, the toner is prevented from being transferred from the cleaning member to the image carrier, thereby obviating defective cleaning. An image forming speed is increased by reducing the interval between consecutive image forming areas. A pressure is caused to act uniformly between the cleaning member and the image carrier in the axial direction of the roller, further enhancing the toner collecting efficiency and toner redepositing efficiency while obviating background contamination.
摘要翻译：图像形成装置包括用于在图像转印之后收集在图像载体上的调色剂的清洁部件，然后将其重新沉积在载体上，使得显影单元可以收集再沉积的调色剂以重新使用。即使当清洁部件的摩擦带电能力由于老化或环境变化而降低时，在调色剂到达清洁部件之前，留在图像载体上的调色剂的电荷被调节为预选的极性，从而提高调色剂收集效率和调色剂重新沉积效率。再次沉积在图像载体上并移动离开清洁部件的调色剂的电荷在增加时被调节到预选的极性，从而减少作用于显影单元的负载。调色剂有效地再沉积在图像载体上，而不考虑由清洁部件收集的调色剂的极性。允许显影单元收集重新沉积在图像载体上的所有调色剂，从而释放图像的背景污染。当清洁构件从图像载体收集调色剂时，防止调色剂从清洁构件转移到图像载体，从而避免了有缺陷的清洁。通过减小连续的图像形成区域之间的间隔来增加图像形成速度。导致压力在辊的轴向上在清洁构件和图像载体之间均匀地作用，进一步提高调色剂收集效率和调色剂再沉积效率，同时避免背景污染。

摘要： An image forming apparatus includes a rotatable image bearing member and a contact-charging member which contacts a surface of the image bearing member. The contact-charging member can charge the image bearing member by applying a predetermined voltage to the contact-charging member so that a potential of the contact-charging member is changed to a required potential for transferring a residual toner that is stuck on a surface of the contact-charging member facing the image bearing member onto the image bearing member while the image bearing member stops rotating. A method for removing residual toner sticking onto a contact-charging member that contacts a surface of the image bearing member changes a potential of the contact charging member to a required cleaning potential for transferring the residual toner sticking to a surface of the contact-charging member facing the image bearing member onto the contact-charging member while the image bearing member stops rotating. The residual toner is then transferred from the surface of the contact-charging member facing the image bearing member onto the image bearing member, and the residual toner sticking to the surface of the contact-charging member facing the image bearing member is then removed.

摘要： An image forming apparatus includes a photoconductive element including a conductive support rotatably supported and a charge injection layer and a surface protection layer sequentially laminated on the conductive support. A charger includes a conductive body for injecting, when a preselected voltage is applied thereto, a charge in the charge injection layer in contact with the surface protection layer. A writing unit exposes the charged surface of the photoconductive element imagewise to thereby locally vary the potential deposited on the photoconductive element and electrostatically form a latent image. A developing unit develops the latent image to thereby produce a corresponding toner image. The toner image is transferred from the photoconductive element to a recording medium. Assuming that the charge injection layer has a thickness of D micrometers, and that the potential deposited on the surface of the photoconductive element by the conductive member is V volts in absolute value, then a ratio V/D is confined in a preselected range that does not contaminate the background of the photoconductive element.
