摘要： The development apparatus of this invention includes a developer supporting body consisting of a rotatable non-magnetic sleeve and a magnet roll fixedly installed within the rotatable non-magnetic sleeve. The development method involves the following steps: a latent image formed on a latent image supporting body is developed or made visible with a two-component developer carried on the developer supporting body in a non-contact manner; a horizontal magnetic field which is orientated in the circumferential direction of the developer supporting body is applied to the developer in an effective development area on the developer supporting body, the effective development area facing the latent image supporting body; and a developer movement promotion magnetic field is applied locally to a part of the effective development area on the developer supporting body so that the developer is expelled from that part of the effective development area and that chains of carrier of the developer in the developer expelled region are slid in the circumferential direction of the developer supporting body. This development method ensures a sufficiently high development performance during the multicolor image forming process without disturbing the toner image formed.

摘要： There is disclosed a dual component developing device for developing an electrostatic latent image formed on a latent image carrier. The system comprises a rotatable nonmagnetic sleeve, a magnetic roll mounted inside the sleeve, and a developer-limiting member made from a nonmagnetic material. The magnetic roll has neighboring magnetic poles which have the same polarity and repel each other. The limiting member is disposed opposite to the repelling magnetic poles and between the position at which the magnetic force produced by the repelling pole located on the upstream side as viewed in the direction of movement of developer is maximal and the position at which the magnetic forces produced between the repelling poles is minimal. Thus, the developing device is capable of forming a thin film of the developer without aging. The amount of the transferred developer depends to a lesser extent on the spacing between the sleeve and the limiting member.

摘要： In a color recording apparatus, charges are applied to a latent electrostatic image carrier by a scorotron having a grid after development of a first latent electrostatic image on the carrier with a first color toner. Thereafter, a second electrostatic latent image is formed and developed with a second color toner. If the charges given by the scorotron have the same polarity as a charging polarity of the first color toner, a potential of the grid is set to be equal to a non-image portion potential of the first latent electrostatic image, or set to have a polarity opposite to that of an image portion potential of the first latent electrostatic image assuming that the non-image portion potential is regarded as 0 V as a reference potential. If the charges given by the scorotron have a polarity opposite to the charging polarity of the first color toner, a potential of the grid is set to have a polarity opposite to that of the non-image portion potential image assuming that the image portion potential is regarded as 0 V as a reference potential.
