摘要： A process for depositing magnetic toner material on electrostatic latent images formed on an image bearing surfaces includes the steps of conveying toner to the developing zone via a magnet roll having a shell and coaxial permanent magnet member rotating in the same directions. In the region of the developing zone, the toner is subjected to both an A.C. magnetic field and an applied A.C. electrical field so as to render the toner electroconductive. The A.C. electrical field has a peak voltage greater than the dark voltage of the latent image, but less than 3,200 volts, and a frequency greater than v/0.3 where v is the advancing speed of the image bearing surfaces in relation to the magnet roll.

摘要： A toner cartridge suitable for use with a developing device of the magnetic brush type using a magnetic toner for an electrostatic recording apparatus including a hollow, cylindrical container closed at opposite ends and formed with a longitudinally extending toner supply opening. The container has a knob at one end and a projection on the outer circumferential surface of the other end. When the cartridge is fitted in a hopper, the projection is inserted in a guide groove formed in an upper portion of the hopper and the cartridge is moved deep into the hopper. Upon completion of fitting, the projection is released from engagement with the guide groove, to allow the container to rotate to feed a charge of magnetic toner from the vessel to the hopper.

摘要： A magnet-brush development process in which the amount of developer powder supplied to a development zone is self-controllable by the rotation of a magnet roll. A permanent magnet member and the shell rotate at different speeds in the same direction in such a manner that developer powder, as a whole, is conveyed on the shell in the direction opposite to the rotation of the magnet roll from a doctor spacing of a developer vessel to an image-bearing material. By controlling the doctor spacing to be larger than the gap between the image-bearing material and the magnet roll, an accumulation of the developer powder occurs on the shell between the doctor spacing and the development zone and is kept to be substantially constant. At the accemulation, an understream of powder moves in the direction of roll-movement towards the powder supply.
