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： In an image forming apparatus, during the course of recording, a cleaning roller is rotated together with an image carrier. The roller frictionally charges toner left on the image carrier after image transfer to the same polarity. A cleaning member electrostatically collects the charged toner. At the same time, a voltage is applied to the cleaning member by a voltage applying device in order to cause it to attract the charged toner, thereby cleaning the image carrier. Hence, even when the toner remaining on image carrier is charged partly to the positive polarity and partly to the negative polarity, the toner can be entirely transferred to the cleaning member by a simple construction.

摘要： The color image forming method of the kind sequentially forming toner images of different colors on an image carrier with developers of corresponding colors stored in a plurality of developing devices, sequentially transferring the toner images to a single paper or similar recording medium one above the other, and returning the toner left on the image carrier after the image transfer to the developing devices color by color, and an image forming apparatus practicable therewith. After the transfer of a toner image of any particular color to the paper wrapped around a transfer drum, a cleaning roller assigned to the above color each collects the toner remaining on the drum and again deposits it on the drum. The drum conveys the redeposited toner to one of the developing devices storing a developer of the same color as the toner.

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.

摘要： An image recording apparatus for recording an image directly on a recording medium by transferring a toner to the medium. The toner is caused to fly toward the medium by small energy to form a high resolution image. A developing roller transports the toner in a predetermined direction. A flat electrode is located in the vicinity of the developing roller. A control electrode is provided on the flat electrode at a position where the flat electrode is remotest from the developing roller, while being electrically insulated from the flat electrode. The control electrode is made up of a number of recording electrodes and has an opening through which the toner may fly toward the medium.

摘要： In an image forming apparatus, a toner collection mode is executed when a series of image formation modes ends and when the image formation mode is continuously repeated a preselected number of times. A toner image sensing mode for sensing a reflection density from a reference toner image is executed every time the image formation mode is repeated a preselected number of times. The apparatus is capable of surely and efficiently removing toner left on an image carrier after image transfer, and collecting the reference toner image with a developing unit. The reference toner image is prevented from contaminating an image transferring unit and a cleaning unit.
