Abstract
PURPOSE: To enable the wide, high and soft magnetic brush effective for development to be obtained by letting the magnetic circuits of magnetic poles of magnet rolls for copying machines assume repulsion circuits.
CONSTITUTION: Magnets 1 are secured to the shaft 2 which is supported by way of bearings 6, 6 in a circular cylindrical sleeve 3 of non-magnetic material to constitute the magnet roll. At this time, if the magnets 1 are let to form repulsion circuits of the same pole to itself, the magnetic fluxes are mutually respulsed and reach far and therefore the magnetic brush becomes high and soft. In addition, the width of the magnetic brush may be set freely by adjusting the distance W between the magnets. The decrease in conveying characteristic by the repulsion circuits may be prevented by applying surface perparation such as shot balsting, knurling, V-grooving, etc. on the outside circumferential surface of the sleeve 3.
