Abstract:
A process for developing electrostatic images, comprising:moving an electrostatic imaging member having an electrostatic image at a member velocity; rotating a shell with a shell surface velocity adjacent said electrostatic imaging member and co-directional with said member velocity; and rotating a plurality of magnetic poles inside said shell, said shell and said magnetic poles bringing a mixture of toner and hard magnetic carriers into contact with said electrostatic imaging member thereby depositing toner on said electrostatic image; said shell surface velocity being greater than a shell surface velocity that creates noticeably greater toner density on leading edges of said electrostatic image than on the balance of said electrostatic image, and less than a shell surface velocity that creates noticeably greater toner density on trailing edges of said electrostatic image than on the balance of said electrostatic image.
