Abstract: Systems, methods, and apparatus are provided for purging charged powder particles from a mixture of ferromagnetic carrier particles and said powder particles. One example embodiment may include a powder purging apparatus comprising a support surface comprising a first side for supporting said carrier particles; a plurality of magnets, arranged on a second side of said support surface for generating magnetic fields at said first side to attract said carrier particles for forming a magnetic brush of said carrier particles, said magnetic fields and said support surface moveable relative to each other; an attracting surface facing said first side and spaced apart therefrom; and a field generator adapted for generating an electrical field between said attracting surface and said support surface for attracting said powder particles away from the carrier particles and towards said attracting surface, wherein said magnetic brush of carrier particles is spaced apart from said attracting surface.
