    摘要： Disclosed is a dry magnetic developer consisting essentially of a particulate shaped article of a composition comprising a binder resin medium and a powdery magnetic material dispersed in the binder resin medium, wherein said composition is composed of a non-pulverizing agglomerate of cubic particles, and particles having a number average particle size of 1 to 10 microns, as measured by an electron microscope, are incorporated as the powdery magnetic material.This magnetic developer is excellent in the image sharpness, the resolving power and the half tone-reproducing property, and is especially effective for developing a positively charged latent image which is formed on a p-type photosensitive plate such as a selenium photosensitive plate or a photosensitive plate comprising an organic photoconductor layer.

    摘要： A magnetic mixture comprising at least two kinds of powders which are uniformly mixed with each other. Each powder exhibits a significant magnetic property when its constituent elements have a predetermined composition ratio. Magnetic properties of each powder are retained in the magnetic mixture which exhibits, as a whole, a soft magnetic property. The magnetic mixture is useful as a raw material for a powder magnetic core.

    摘要： An electrostatic copying apparatus having defined therein a copying paper conveying passage extending from a paper feeder to a paper receiver through a transfer zone and a fixing zone. In the transfer zone, a toner image on an electrostatographic material is transferred to a copying paper, and then fixed in the fixing zone. The electrostatic copying apparatus includes a paper swerving device disposed within the paper conveying passage and between the fixing zone and the paper receiver and adapted to be selectively held at a non-operating position at which it permits the copying paper to be discharged into the paper receiver through the paper conveying passage and an operating position at which it swerves the paper from the paper conveying passage; a paper re-feeding device for feeding the received paper into the paper conveying passage at a position upstream of the transfer zone; and a paper returning device for returning the swerved paper to the paper re-feeding device while its front and back surfaces are reversed, the swerved paper having been swerved from the paper conveying passage by the paper swerving device held at the operating position. Thus, the apparatus can produce an image on both surfaces of the paper as required.
