Abstract: PURPOSE:To stabilize a toner carrying quantity on a magnetic field generating layer and to carry out development so that base fogging and density irregularities are reduced by bringing at least, a part of a developing roller into contact with a drum-like thin film member and its inner peripheral side surface and providing a driving roller generating a magnetic field. CONSTITUTION:The developing roller 9 is rotated/driven and composed of the driving roller 10 generating the magnetic field, and the drum-like thin film member 11 on its outer periphery. Magnetic toner 8 is held on the thin film member 11 by the leakage magnetic flux of the driving roller 10, and regulated to a proper quantity by a thin plate spring-like elastic blade 13. In this state, the developing roller 9 is rotated to carry the thin layer toner 8. It is slid by a magnetic flux, to receive triboelectrification and the injection of a charge, so that the toner on the thin film member has a stable electrifying quantity to carry out sufficient development. The toner 8 is stuck to a latent image carrier 1 to actualize an electrostatic latent image. At this time, a developing electric field can be emphasized by pressing the thin film member to the latent image carrier, and a distance between the latent image carrier and the thin film member is regulated by the thickness of a toner layer, so that the developing electric field is stabilized, and a high-density and high-resolution image can be stably formed without having the base fogging.

Abstract: PURPOSE:To measure the magnetic permeability of a soft magnetic body which varies with strain generated by torque by fixing a magnetostrictive soft magnetic body to the periphery of a torque transmission shaft and providing a couple of arcuate coils across the shaft. CONSTITUTION:The sensor consists of the torque transmission shaft 1, soft magnetic body 2 wound around the transmission shaft 1, and coil 3 which consists of a couple of arcuate parts arranged opposite each other across the transmission shaft 1 and soft magnetic body 2, a detecting circuit 4 which measures the inductance value of the coil 3, etc. Both parts of the coil 3 are wound, for example, spirally so as to establish a magnetic field at right angles to the transmission shaft 1. Then the coil 3 is divided, so it is fitted to the transmission shaft 1 through a coil opening part 5, and magnetic flux is supplied to the whole area of the soft magnetic body 2 because of the arcuate shape. When torque is applied to the transmission shaft 1, the soft magnetic body 2 generates tensile and compressive stress at 45 deg. to the shaft direction and the magnetic permeability of the soft magnetic body 2 is reduced by magnetostrictive effect. Thus, the quantity of the torque is measured.
