摘要:
In electrostatic latent image developing process capable of effecting either positive or negative reproduction a magnetic toner of a high resistivity is controlled to form a magnetic brush having a potential insufficient for development. The toner chain constituting the brush is separated under the influence of an electric field between the developing roll and the image carrier, to produce toner particles having one polarity continuing with the developing roll, and particles of the opposite polarity transferred to the carrier.

A rotation sensor functioning as both a rotation-angle sensor and a torque sensor is provided which, when applied to a steering sensor for an automobile, for example, permits reduction in the number of components and thus in the weight of the automobile and contributes to conservation of global environment. The rotation sensor has slip rings covered with conductive synthetic resin having small coefficient of friction, allowing the contact pressure of brushes disposed in sliding contact with the slip rings to be kept low and the life duration of the slip rings to be prolonged. Further, no metal powder is produced when the brushes slide on the respective slip rings, and it is therefore possible to prevent the formation of unwanted insulating film.
