摘要： An image forming apparatus includes a first developing device and a second developing device. The second developing device acts on an image bearing member already having a first toner image produced by the first developing device to form a second toner image. The second developing device has a developer carrying member to which a vibratory voltage is applied. A duty ratio of the vibratory voltage is controlled.

摘要： An apparatus (20) for developing an image region recorded on a photoconductive surface (12) with a dry developer material. A transport (52) moves the dry material closely adjacent to the photoconductive surface (12). The charge induced on the transport (52) by the charge on the photoconductive surface is controlled (58,60) to electrically bias the transport to a potential intermediate the potential of the image region and non-image region of the photoconductive surface.

摘要： An apparatus (36) in which conductive developer material is transported by development means (38, 40) in to contact with a region of a surface (12) having electrostatic latent images recorded thereon. An electrical field generating arrangement (74, 81, 83) provides an electrical field in the development region, and the developer material develops the latent images. In one mode of operation, the electrical field is substantially perpendicular to the surface (12) over one portion of the region and substantially non-perpendicular thereto over the remaining portion of the region. In another mode of operation, the electrical field is substantially perpendicular to the surface (12) over the entire region.

摘要： A developing device includes a developing roller, a magnetic roller, a capacitor, a transformer, and a switching portion. The magnetic roller supplies toner to the developing roller or takes off the toner from the same. The capacitor is connected to a primary of the transformer, and the developing roller is connected to a secondary of the same. During a period while the voltage between electrodes of the capacitor is changing, the switching portion changes the duty ratio in a predetermined second time slot in which current flowing in the switching portion is smaller than that flowing in a first time slot.
