Because latent magnetic images formed in magnetographic machines tend to be highly over developed, a large percentage of the toner on the developed image (around 40%) must be removed in order to achieve an acceptable background level in the non-image areas. Consequently, unless this toner is continually returned to the development sump holding toner, the toner or developer consumption rate becomes prohibitively high. Generally, toner recovery devices are either expensive or high energy users or both.
