ABSTRACT:
Disclosed is an improved dies set for magnetizing a cylindrical or columnar magnet adapted for use in an electrostatic developing apparatus of magnetic-brush developing type. The dies set is intended for imparting axially extending and circumferentially alternating magnetic poles to the periphery of the cylindrical columnar permanent magnet. The magnetizing dies set of the invention has a specific pattern of magnetic pole arrangement for rendering the distribution of magnetic attracting force, which is to be permanently applied to the peripheral surface of the columnar magnet in the magnetic developer, so that the attracting force becomes as uniform as possible, over the entire periphery of a shell surrounding the permanent magnet.
