Abstract

Measurements of two component development using a magnetic brush with a rotating magnetic core, polymeric toner, and insulative, magnetically hard carrier are compared to the behavior of conventional two component development using a magnetic brush with a fixed magnetic core and insulative carrier. Significant differences are observed in the characteristics of the two technologies.For rotating magnetic brush development, the mass area density for deposition of toner onto a conductive substrate has exponential time dependence, similar to the charging of a capacitor. The Equilibrium Theory for conventional development predicts mass area densities proportional to the ratio of roller speed to substrate speed. The difference in behavior can be attributed to the agitation of the developer nap produced by the rotating magnetic core development system.
