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.

摘要： An apparatus and method for recording an image using a transfer-type recording mechanism are such that a layer of an intermediate transfer element is removably formed on a surface of an intermediate transfer medium. The intermediate transfer element includes an ultraviolet stabilizer and a powder mixture. The intermediate transfer layer is capable of being dissolved and swelled by applying an ink liquid on the intermediate transfer medium and enables a viscosity of the ink liquid residing thereon to be increased. An image is produced on the intermediate transfer medium by supplying the ink liquid thereon. The image is then transferred to the recording medium, so that a high quality image is produced without any blurring, mixing or penetration of the ink liquid.
