    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.
