    摘要: A charger capable of reliably and uniformly maintaining a discharging gap formed in the vicinity of a contact portion between a charging member and a photosensitive member. A charging member 101 is arranged by supporting and fixing both ends of a flexible film 102 by means of support members 103 to 105. The film 102 forms a flexible portion oriented downwardly from fixed ends S1, S2. The film 102 is brought into contact with the member 110 to be charged in a state in which an unsupported side of the film 102 is oriented toward the downstream side in the rotating direction of the member 110 to be charged. Then, the film 102 is brought into contact with the member 110 to be charged in a contact area N, and the radius of curvature of the film 102 in a zone P2 located downstream of that zone N in the rotating direction of the member 110 to be charged becomes smaller than the radius of curvature of the film 102 in an upstream zone P1.

    摘要: Based on a video signal, a toner dot counter and an off dot counter detect a size of a toner dot portion to carry an adherent toner thereto and a size of an off dot portion not to carry an adherent toner, respectively. Reference is made to a look-up table based on the detection results, so as to retrieve a coefficient Kv corresponding to a combination of the sizes of the toner dot portion and the off dot portion. A count value Cdot given by the toner dot counter is multiplied by the coefficient Kv, while the resultant product is integrated by an accumulator. An integration value for an image of one page is multiplied by a coefficient K0 equivalent to a toner adhesion percentage of solid image. Thus is determined a toner consumption TC on the page image.

    摘要: A method for replenishing depleted portions of an ink sheet including a conductive ink layer on a dielectric layer wherein portions of ink have been transferred to a transfer medium. Conductive replacement ink material is supplied to the ink sheet and an electric charge is induced in the replacement ink and opposite charges are induced at an electrode on the opposite side of the dielectric layer. Replacement ink contacting the dielectric layer at the voids will adhere to the ink sheet, but charges in the replacement ink contacting the non-transcribed ink regions will flow to the conductive ink layer and will not adhere to the ink sheet.

    摘要: A method and apparatus for replenishing depleted portions of an ink layer of an ink sheet formed with a conductive ink layer disposed on an insulating layer from which ink has been transferred, without unintentionally supplying ink to undepleted portions of the ink layer are provided. Electrically conductive replacement ink is charged and supplied onto an intermediate transfer roller having a dielectric layer disposed on an electrically conductive layer. Charge is supplied to the insulating layer side of the ink sheet and replacement ink on the intermediate roller contacting the ink sheet at depleted regions of the ink sheet is transferred from the intermediate roller to the depleted portions by electrostatic attraction and not to undepleted portions. The method and apparatus are adaptable for multi-color ink sheets and can be employed in connection with a printer or image forming device.
