    摘要： An apparatus for developing a latent image on a latent image carrier includes a toner carrier and multiple electrodes arranged at intervals on a surface of the toner carrier. A potential difference is formed between even-numbered electrodes and odd-numbered electrodes of the electrodes by applying a first pulse voltage to the even-numbered electrodes and a second pulse voltage to the odd-numbered electrodes so that toner on the surface of the toner carrier moves back and forth between the electrodes, where the first and second pulse voltages are in different phases, and the toner moving back and forth between the electrodes is conveyed to a position facing the latent image carrier by movement of the surface of the toner carrier and thereby caused to adhere to the latent image on the latent image carrier.

    摘要： A development device includes an open-ended housing, a rotatable roller, an array of multiple primary electrodes, a voltage source, a sealing member, and a secondary electrode. The housing accommodates toner for application to the photoconductive surface through an end opening thereof. The roller has an outer circumferential surface to deliver the toner from within the housing to a development zone. The array of multiple primary electrodes are aligned with each other on the roller surface. The voltage source applies a periodic pulse voltage to at least a subset of the primary electrodes to generate an oscillating primary electric field. The sealing member seals clearance between the roller surface and an edge of the end opening downstream from the development zone. The secondary electrode generates a secondary electric field to force the toner from the sealing member toward the roller surface to prevent premature removal of the toner.

    摘要： A disclosed developing apparatus employs a flare roller that is a toner carrier in which electrodes of two different phases are provided at fine intervals. Density irregularities or scumming in a developed image due to a potential difference between the flare roller and a latent image carrier are prevented by maintaining a constant potential on the flare roller surface. A voltage is applied to the electrodes on the flare roller such that an electric field that varies with time is generated between the electrodes, whereby a toner cloud is produced by the movement or hopping of toner over the flare roller. Thereby the toner attaches to a latent image on the latent image carrier, thus developing the latent image. In one embodiment, a bias with an average potential equal to an average potential of the bias applied to the electrodes is applied to a toner layer thickness regulating member.

    摘要： A developing device for a toner powder cloud development system, which can achieve high image quality and can be made compact. The developing device has a two-component development unit, a toner carrier, and an alternating current power source. The toner carrier, which is arranged opposing a latent image carrier, has a plurality of electrodes disposed in a line in a prescribed direction on the surface thereof, and mutually insulated. The alternating current power source supplies a voltage such that an electric field across the plurality of electrodes is temporally switched. The inter-electrode electric field causes the toner being carried on the surface of the toner carrier to carry out hopping, thereby forming a toner powder cloud and carrying out development. The movement speed of the latent image carrier and the linear velocity of the toner carrier are set at approximately equivalent speeds.
