Abstract

PURPOSE: To everage the anevenless of toner layers and prevent the occurrence of density unevenness by so forming magnetization regions on a magnetic cylindrical body that the magnetic lines of force formed on the surface of a non-magnetic material sleeve go to the directions zigzag to the circumferential direction of the sleeve.
CONSTITUTION: With the magnet roll provided with a cylindrical body 1 of magnetic material and a non-magnetic sleeve supported relatively rotatably by way of a spacing on the peripheral surface thereof, magnetization regions are so formed to the cylindrical body 1 that the directions of the magnetic lines of forces on the surface of the non-magnetic material sleeve made by the cylindrical body 1 have the components rectangular to the circumferential direction. When the magnetization regions 3 are so formed that their areas vary on the X axis, and if it is assumed that the magnetic flux densities per each unit area on the magnetization regions 3 are uniform, then the toner is subsequently conveyed by assuming the zigzag routes as shown by the arrow.
